Stoke City have enjoyed a slight up turn in form since Michael O'Neill was appointed as the club's new manager, with the Potters securing three wins from their opening seven Championship matches under the Northern Irishman.

O'Neill guided the Potters to two successive wins in his first two matches in charge against Barnsley and Wigan Athletic, before Stoke suffered three straight defeat against Cardiff City, Blackburn Rovers and Hull City, which somewhat damped renewed hope the 50-year-old could turn their season around.

However, a much-needed 3-0 win at home to fellow strugglers Luton Town and a goalless draw against Reading last weekend, has at least brought the Potters back in touch with the teams just above the relegation zone in the Championship.

One player, though, who has found his game time limited since O'Neill took charge is Tyrese Campbell, who has been a victim of the Northern Irishman's decision to alter the Potters' formation to more of a 4-3-3, which has seen the 19-year-old fall down the pecking order and behind the likes of Sam Vokes, Lee Gregory, Scott Hogan and Mame Biram Diouf.

Campbell had been enjoying a breakthrough campaign before O'Neill's arrival, having made 13 appearances in the Championship and registered his first league goal for the club during their 2-0 win against Fulham.

O'Neill, though, appears to be unsure over whether Campbell has the ability to lead the line up front on his own, which has seen him left out of the squad recently and looking unlikely to force his way back into the side during the rest of the festive period.

The striker's situation has reportedly alerted both Celtic and Rangers, with the two Scottish giants interested in making a potential move for the 19-year-old during the January transfer window to bolster their attacking options.

Here, by taking a closer look at Campbell's so far this season, we assess whether the forward would be good enough to make the move to either Celtic or Rangers in January...

Despite being currently out of favour under O'Neill, Campbell has still managed to make 13 appearances for the Potters in the Championship during the opening half of the campaign, in which he has shown glimpses of his potential to develop into an effective striker.

Campbell has demonstrated his ability and composure in possession having recorded a 70.9% passing accuracy so far this campaign, which is impressive considering he would have been receiving the ball in the final third and having to link up the play with Stoke's other attacking players.

That suggests he would have the ability to come into either Celtic or Rangers' line-ups and allow them to continue to build the play through the third, as both Neil Lennon and Steven Gerrard encourage their players to do when in possession.

The striker has also shown he is not afraid to fire in efforts on goal, having averaged 2.69 with an expected goals tally of 0.49 per game, which demonstrates he has the confidence needed to express himself in the final third when he has the chance - and he would likely have more chances to get shots away playing for both Celtic and Rangers who tend to create more going forwards.

The 19-year-old has also shown he has the ability to take on players in the final third, averaging 4.49 dribbles per game, and that is something which both Celtic and Rangers need from their attackers when they are often trying to break down teams with all their players behind the ball.

Campbell has also demonstrated he is effective at winning the ball back in transition, having made 1.79 interceptions per game, which would be very useful for both Celtic and Rangers when they are looking to counter on teams after turning over possession.

One area of his game that Campbell will be needing to work on is his hold up play, and he has only won 31.8% of his aerial duels, but that should improve the more time he is given to develop and learn the game, so should not be too concerning for any potential suitors.

Therefore, given Campbell could be available fairly cheaply and considering the potential he has to be developed further, then he would be a very useful addition for either Celtic or Rangers in January.
