Preston North End are set for a busy summer transfer window as Frankie McAvoy gets to grips with his squad, but you're unlikely to see any big players head out the exit door at Deepdale.

Since they've returned to the Championship, the Lilywhites have had a few players that they've cashed in on, which is necessary due to the lack of financial turnover the club produces compared to many of their league rivals.

Jordan Hugill, Greg Cunningham and Callum Robinson have all departed for significant transfer fees since 2018 but it doesn't look like any big sales will be made this summer as there hasn't been a standout North End player from the previous season that would be courted by other clubs.

The squad have a chance though to increase their value next season though and to perhaps put themselves in the shop window - let's look at the 10 most valuable current North Enders right now and let us know if you disagree with the rankings!

If this list was being done three years ago, then Maguire would have probably been the most valuable player at Deepdale and he may even have been sold that summer.

He arrived from Cork City in July 2017 as the most prolific man in Irish football, but the real test was ahead of him as he looked to step up a number of levels into the Championship.

Maguire passed that test by scoring 10 goals in 24 league games for North End in his first season, but that's when the problems and regression started.

The striker missed months of his debut season at PNE due to a hamstring injury and in the summer of 2018 he suffered another setback with his hamstring, and since then he's lost the explosive pace that fans were in awe of when he first joined.

His seasonal league goals since that first season have been three, five and three, which goes to show that Maguire isn't the player he once was and it's clear to see when you watch him play.

Considering he was brought in in 2019 for between £1.5 million and £1.8 million - a fee that is still disputed amongst PNE fans - Bayliss has failed to make an impact in his two years at North End but he hasn't really been given many chances.

If Bayliss had found himself in the first-team since his arrival then he definitely wouldn't have been as low down as ninth, but under McAvoy he has the chance to fulfil his potential.

He was finally given a chance on the final day of the season against Nottingham Forest and paid back the faith shown in him by finding himself in the right place to divert Scott Sinclair's shot over the line, then played a wonderful ball to Ched Evans who set up Liam Lindsay for the winning goal.

Should Bayliss get more minutes next season, expect his value to shoot up if he can show what he's really made of.

Due to having one year left on his contract and his age, Sinclair is lower down the list than you might have anticipated but in terms of transfer value it makes sense.

Despite his experience and goalscoring exploits, Sinclair wouldn't fetch a decent fee nowadays as he's 32 years old - he still holds strong value to North End on the pitch though.

Sinclair finished the season as PNE's leading scorer with nine goals - which would have been 10 if Tom Bayliss didn't get in the way of his shot against Nottingham Forest - and he led the way for goals even though Frankie McAvoy didn't seem to favour him when he took over.

The experienced winger could be the answer through the middle of the park if McAvoy sticks with his 3-5-2, but whatever happens his transfer value still remains pretty low.

Potts may split opinion amongst North End fans but there's no doubting his effectiveness in certain games - especially away from home.

He brings a lot of energy and legs in games away from Deepdale especially and you could perhaps say he's under-rated by a section of the supporter base.

Potts scored five goals in the season that has just finished, playing mostly off the right wing but if McAvoy sticks with his system then the 26-year-old will be battling with Daniel Johnson and Alan Browne for a place in the attacking midfield position.

He's another player with just a year left on his deal though but due to his contributions and age he remains higher in the list than the likes of Sinclair and Maguire.

Barkhuizen is another who is yet to sign a new contract with his current deal expiring next summer, and when he's on form he's one of those players that could be at a top Championship team.

Last season though wasn't the 27-year-old's best though in terms of goal contributions as he scored just four times in 45 league appearances - way down from his best of nine the season prior.

What Barkhuizen has proven though is that he's really versatile - McAvoy chose to deploy him as a wing-back for multiple games in his caretaker spell as he ditched natural wingers and that could be a role for him going forward.

It remains to be seen if he will be offered a new contract but you'd expect that to happen and his value will only increase if he pens a new deal.

He's not always been a regular in North End's line-up, but Storey seems to have come of age in recent games as a part of McAvoy's defensive unit.

The young defender struggled for game-time last season, playing just 10 Championship matches, but the sale of Ben Davies has given the 23-year-old a new lease of life and he's started every single match for North End since the win over Blackburn in February.

Storey isn't the finished article by a long shot, but he was part of a back-line that kept five clean sheets in eight games under McAvoy at the end of the season and should he stick with three centre-backs in one team, you'd imagine that he'd be one of the first names on the team-sheet.

If his performances stay at the level he was showing in recent weeks, then there's every chance Storey could attract transfer attention this time next season.

The newly-crowned PNE Player of the Season has filled the void left by Ben Pearson and he's also seemingly taken his disciplinary record as well.

Ledson didn't win the award for his goalscoring or creativity, but for his battling performances in the engine room and he's won the hearts of PNE fans for his passion and drive on the pitch.

There was always the belief amongst fans that Pearson didn't attract big transfer offers because of his discipline on the pitch, and Ledson may end up going that same way as he picked up 10 yellow cards this past season.

But if he carries on improving the way he has in the last 12 months, then bigger Championship clubs may start to take notice if they need an all-action midfielder.

North End got fans very excited in January when they confirmed the acquisition of Whiteman from Doncaster Rovers, who seemingly had half the Championship watching him at the time.

PNE paid around £1.5 million for his services and in the first few months of his performances it looked as though Alex Neil had brought him in to replace Ben Pearson as the quarterback of the team.

Whiteman doesn't have Pearson's ability to break up the play though and looking at his time at Doncaster he looks to be effective around the opposition box, having scored eight goals last season before making the move.

The midfielder broke his North End duck with a header against Derby County in April and more of those goals next season could see his value accelerate.

There was bound to be transfer interest in Johnson last season after a Championship campaign where he scored 12 times - and a move to Scottish giants Rangers looked to be in the offing.

They couldn't match North End's valuation for the Jamaica international though and Johnson remained at Deepdale, eventually signing a new deal months later to keep him around until at least 2023.

Johnson though will admit that his 2020/21 campaign wasn't his finest - the transfer speculation to start the season may have hindered him and by the middle of the season he wasn't starting games under Alex Neil.

We all know what he can do from midfield though - 'DJ' has scored 37 goals at this level over the years for North End and if McAvoy can get the best out of him once again then that transfer value that the club held over him last summer should rise once again.

Johnson may have competition though for a starting spot next season as in McAvoy's 3-5-2 system there is only room for one attacking midfielder - and captain Alan Browne may take that role up.

Despite playing at right-back and deeper in midfield at times, the Ireland international's most effective role is getting into the box and scoring goals.

We saw that in the 2018/19 season when he scored 12 times in 38 games and surprisingly it didn't lead to transfer interest from bigger clubs.

On the goalscoring front Browne has had a quieter few years but he will soon be hitting his peak now he's 26 years old and if he's given the freedom to drive up the pitch, then we could see the best of PNE's number 8 next season and become the club's most valuable player - if he isn't already.
