What Kyle Walker did that massively 'disappointed' Pep Guardiola before he was sent to AC Milan

Kyle Walker did one thing that massively 'disappointed' Pep Guardiola before he moved on loan to AC Milan, it has been reported.

Walker moved to Milan on a temporary deal until the end of the season, and may well have now played his last game for City as the Italian club have an option to buy the 34-year-old as part of the loan contract.

The England international made his debut for his new club in their 1-1 draw against Inter Milan in the Milan derby over the weekend - and Italian media made their feelings clear on him.

Walker has stated that he left City in order to have more game time, as he has slipped down Guardiola's pecking order this season.

The Spaniard said he would not stand in the right-back's way if he wanted to leave the club in January, and a deal was quickly agreed with Milan.

But The Athletic claim that Guardiola was left 'disappointed' by something Walker did before he left the Etihad Stadium.

Walker is said to have told City's sporting director Txiki Begiristain of his desire to leave the club, rather than approach Guardiola directly.

The City boss is said to have felt that the pair had 'such a good relationship' that the 34-year-old would be able to 'come to him with anything'.

Walker is said to have agreed to the move after speaking with Milan sporting director Zlatan Ibrahimovic, and is not expected to return to City next season despite having another year left on his contract by then.

There appear to be no hard feelings between himself and Guardiola, though, with the Spaniard publicly stating ahead of City's 3-1 win over Chelsea last month: "Thank you [to Walker] so much for the seven years you've been with us. For the amount of trophies, for the consistency, for being a very important figure.

"I said personally to him, and I said in front of the group, that I wish him all the best, for him and his family."
