​Former ​Manchester City defender, Joleon Lescott has warned ​Aston Villa star, Jack Grealish over making a move to Old Trafford in the summer, claiming that there is no guarantee that the midfielder will realise his ambition of playing in the Champions League if he does join them.

​Manchester United have been heavily linked with Grealish over a potential transfer in the summer with a fee of £70million being mooted after they have been impressed with the 24-year-old's displays this season.

The player too is understood to be interested in joining the Red Devils as he looks to make a step up in his career - though Lescott believes that it may not be the case with the club currently struggling under manager, Ole Gunnar Solskjaer.

"When you look at the spectrum of teams, Manchester United are still a big club but in terms of Grealish’s ability, if he leaves Aston Villa he’s going to want to play Champions League and that’s not guaranteed at United, even in the future. ‘I would love to see him test himself in the highest level because I think he’s capable of playing at real heights," he said as per ​Metro.

"In terms of if he was going to move to United, it would obviously be a great move for him because it is Manchester United. ‘But, in terms of how he can test himself against the very best, is he going to be able to do that at United as they’re not guaranteed Champions League football?"

European giants, Barcelona and Real Madrid too are said to be interested in signing the playmaker who has been in brilliant form for Villa this term, netting nine goals in 27 appearances so far.
