Danny Mills has claimed John Stones future at Manchester City is in major doubt despite the exit of Vincent Kompany this week.

The club captain announced on Monday he is quitting the Premier League giants after the stunning treble success to become player-manager of Anderlecht.

That would seemingly be a major boost to Stones’ hopes of being a mainstay of the City starting line-up next season after he was squeezed out of the side by Kompany in the final months of 2018-19.

But ex-City defender Mills has told Football Insider that Pep Guardiola is not totally convinced by Stones and the club’s pursuit of Harry Maguire could push him down the pecking order at the Etihad Stadium.

“The biggest problem is replacing Vincent Kompany, not only as a player but also as a man and communicator and leader with all that experience,” Mills said. “He is the captain and the ultimate professional all the way through the club’s rise over the last decade.

“Who is going to be the person who sets the standards in the dressing room now? Pep has not trusted John Stones in big games. There is clearly something there that Pep thinks, ‘he’s not quite for me’.

“He would rather play Kompany while he is possibly 90 per cent fit. Now, they are talking about Harry Maguire. Where does that leave John Stones?”

The England international, 24, started only two of City’s final nine Premier League matches of the season, was omitted from the XI for all four of their Champions League knockout ties and was on the bench for the FA Cup final and semi-final.
