The summer of change at Ashton Gate has begun, with Bristol City confirming the departures of a significant chunk of their playing squad when published their retained and released lists yesterday. 

The Robins staggered through the latter part of the Championship season and finished 19th, which highlights the size of the task facing Nigel Pearson.

He'll want to add some quality to his squad this summer but has made no secret of the fact that he feels it could take up to six windows to do so.

Given that money could well be tight over the next few months, Pearson may feel that he needs to sell a few players to generate some cash and invest in the squad.

With that in mind, we've outlined who we believe to be the top 10 most valuable players in the Robins squad.

Do you agree? Let us know your thoughts on social media...

We start our list with Adam Nagy and Zak Vyner.

This term, Nagy has showed us why City spent more than £2 million to sign him in 2019. The 25-year-old was unconvincing in his debut season at Ashton Gate but despite the Robins' struggles in 2020/21, he's showed he's got what it takes to cut it in the Championship.

Don't be surprised if a strong European Championships with Hungary sees his stock skyrocket ahead of next season.

Alongside Nagy is Vyner, whose emergence has been another huge positive for the Robins this season.

Whether it's in defence or holding midfield, the 24-year-old has brought composure and poise to the City side this season.

It's going to be exciting to see just how far the academy product can go.

City got an absolute bargain when they signed Joe Williams from Wigan for £1.2 million last summer because he's worth a lot more than that.

Though the midfielder hasn't really had a chance to prove himself this term due to injury, you'd expect the former Everton academy player to show his worth next term.

With more than 100 Championship appearances under his belt already, Williams has established his quality at this level already while at 24, he still has room to grow.

The tenacious midfielder could well become a key man under Pearson moving forward and increase his value even further.

At eight is Tyreeq Bakinson, whose stock is high after making strides in his development this season.

The 2020/21 campaign has ultimately been a disappointing one for City but Bakinson's emergence has certainly been one of the clear positives.

Having spent last season out on loan, the midfielder was first handed a chance by Dean Holden and has been a regular fixture for the Robins – even showcasing his qualities as a goalscorer at points.

Premier League clubs are understood to have been sniffing around him, which will likely have pushed his value up somewhat.

Even so, he still has a fair way to go to compete with some of the players higher up this list.

Had Andreas Weimann not suffered an ACL injury back in October, he would likely be ranked higher on this list.

As it is the 29-year-old forward slots in at number seven, in part because we don't yet know how well he's going to bounce back from his injury.

Since arriving at Ashton Gate, Weimann has been a reliable contributor of both goals and assists in the final third but his game is all about energy and running, which makes his recovery from injury all the more important.

With more than 100 Premier League and 200 Championship appearances under his belt, the Austrian has proven his quality time after time.

He may be 30 now but there can be no arguing with Nahki Wells' place on this list.

Goalscorers are so often the players that demand the highest transfer fees and though the 2020/21 campaign has been far from his best, he's proven himself a man that knows where the net is.

It cost City in the region of £5 million to sign him from Burnley last January and though he's not in the best touch, were they to cash in you feel there would be a fair few clubs – in the Championship and elsewhere – willing to spend to sign him.

Given his injury issues in recent years, it may shock some people to see Jay Dasilva feature so high on this list but he's a player with undeniable talent.

When he's at his best he's among the best left-backs in the division and that should be reflected in his value.

If he can string a run of games together next season, Dasilva will surely be able to remind everyone of his quality.

It's easy to forget that the Chelsea academy product is still just 23 and looks to have a very bright future ahead of him.

Dan Bentley was deservedly named City's Player of the Season for 2020/21 and there's a strong argument were it not for his consistent excellence between the sticks, the Robins could've been relegated.

He often flies under the radar but Bentley's quality is well known in Bs3 and his value reflects that.

At 27, the shot-stopper is likely just entering his prime and, according to the Bristol Post, has generated some Premier League interest ahead of the summer.

The South West club should be looking for a fair significant fee if they're to let him leave in the upcoming window.

The City skipper features at number three on our list on the back of what has, for the most part, been an excellent season.

Tomas Kalas is the Robins' record signing, having joined for a fee in the region of £8 million in 2019, and he showed since that he has proper quality.

It would be a surprise not to see Pearson look to build his side around Kalas moving forward but you feel if they did decide to offload the 27-year-old, he would command a significant fee.

Hopefully from a City perspective, we don't find out just how much any time soon.

Han-Noah Massengo looks like a player with a very bright future.

It's hard to believe at times that the Frenchman is still just 19 but that's what makes him so valuable.

Massengo looked to be drifting slightly at points this season but over the last few months, he's been one of City's best players and served a reminder of what a talent he is.

It was not cheap when the Robins signed him from Monaco back in 2019 but you feel they'll be looking for more than that should any of the reported Premier League interest turn into transfer offers.

The 2020/21 campaign has been a breakthrough year for Antoine Semenyo, who has shown that he's not just a promising young player anymore.

Five goals and seven assists in arguably the worst attacking team in the Championship is not a bad return and the 21-year-old appears to have turned heads in the Premier League.

Crystal Palace, West Ham, and Wolves are just three of the clubs linked with Semenyo but you feel City will be looking for a significant fee if they're to part with their young star any time soon.

He's surely one of the players that fans are most excited to watch when they're allowed back to Ashton Gate.
