Manchester City have accepted AC Milan’s formal offer for Kyle Walker.
The deal agreed is a loan with an option to buy the England international permanently in the summer.
The option is worth for around £4.2m (€5m), according to Sky in Italy.
Walker will arrive in Milan today around lunchtime and will go to a hotel before undergoing a medical in the afternoon.
He will go to AC Milan's headquarters, Casa Milan, to sign the contract.
Walker has helped City win 17 trophies, including six Premier League titles and the Champions League, since joining the club in a £50m deal from Tottenham in 2017.
He was close to joining Bayern Munich after City's treble win in 2023 but signed a contract extension to keep him at the club until 2026.
On the success City have had with Walker, Guardiola said: "We cannot understand the success we've had these years without Kyle. It's impossible.
"He arrived eight years ago with us and we start to win, win, win, win and he has been important for the national team and of course with our team."
Sky Sports' Lewis Jones:
A parting of ways between Walker and Manchester City does make sense for both parties.
Walker may have asked to leave but there will not be much resistance from the decision-makers at the club based on the clear decline of the England international's powers this season.
A player who has built his career on being almost unbeatable in one-on-one duels is now an easy target to exploit for opposition wide players.
Even Timo Werner, who is suffering with form and confidence issues at Tottenham, showed Walker a clean pair of heels to set up Spurs' fourth goal in that chastening defeat for City earlier this season.
It led Sky Sports' Gary Neville to say: "You don't see that very often, but we've seen it a few times in the last couple of weeks. Vinicius Junior, Kylian Mbappe, he's handled them all, Walker, but he's struggling."
Walker's errors are not just odd ones either, they are bringing catalogue vibes. As the with-and-without statistics suggest, his presence has become a hindrance rather than a help for Guardiola.
