Aston Villa manager Dean Smith and assistant John Terry

Danny Mills suggested that big clubs may be unconvinced that Aston Villa midfielder Jack Grealish is disciplined enough to play in one position.

Speaking exclusively to Football Insider correspondent Laura O’Leary, the former England international admitted that he thought Grealish ends up having to play everywhere on the pitch for Villa due to them relying on him.

Villans boss Dean Smith recently confirmed that no member of his squad has a release clause in their contract and that includes Grealish.

Mills explained that there no concerns about Grealish’s talent as he has “untold ability” but added that big clubs like a player of his position not to dart everywhere on the pitch, so they may be unconvinced by him.

When asked how much Grealish would cost a club given the Villans don’t have to sell him and he has no release clause, Mills told Football Insider: “Jack Grealish is a really interesting one.

“The doubts on Jack Grealish are…does he have untold ability? Yes, without a shadow of a doubt. Can he be a match-winner? Yes.

“He’s got so many attributes, but I think the problems he has got at Aston Villa the moment is that because he is such a star, he’s having to do too much.

“When you look at other players in his position, they just stay in their little pockets, the way that Man City play, De Bruyne and Silva…they sit in those pockets and don’t come out of them.

“Grealish has to go and play everywhere, he has to go get the ball off the centre-halves, it’s almost as if he is having to do too much.

“And it’s whether if a big club is interested…can he be disciplined enough to stay in one position? Just be a No.8 or whatever it may be and stay in that little pocket all the time.

“He’s an undoubted talent with experience talent and to get him out of Villa they going to want an extortionate fee, so it’ll be near on impossible to get him.”

Grealish has featured 18 times across all competitions for the Villans, scoring seven goals while registering five assists.

The 24-year-old has risen through the club’s youth system to be one of the club’s star players and is contracted to stay with Villa until 2023.
