Mateo Kovacic, a midfielder for Chelsea, reportedly has a personal contract with Manchester City.
The Croatian international's contract expires the following year, and Chelsea is eager to move players who still have one year left on their contracts rather than letting them depart on a free transfer next summer.
According to Sports Mail, Chelsea have authorized Man City to speak with Kovacic about a transfer.
And according to Fabrizio Romano, the Chelsea midfielder has officially signed a contract with the Premier League champions.
After the Champions League final, the teams are anticipated to reach an agreement on a price.
Kovacic declared on Thursday that he is prepared to 'change surroundings' and quit Chelsea this summer after having a 'really horrible season' at Stamford Bridge.
The 29-year-old midfielder acknowledged that, with only one year remaining on his current Blues contract, he is extremely likely to depart the west London club this summer before Croatia's Nations League semi-final matchup against the Netherlands the following week.
Amid rumors of a possible transfer to the Etihad, Kovacic again praised Manchester City, calling Pep Guardiola's Treble-chasers a "top team."
If City are unable to extend Ilkay Gundogan's contract, they will be in the market for a new midfielder. The out-of-contract captain has drawn interest from Barcelona, Arsenal, and a few Saudi Arabian teams.
After making an impression on Guardiola while playing for Real Madrid and Chelsea, Kovacic is anticipated to sign with the Premier League and FA Cup champions for the upcoming campaign.
"I still have one year left on my Chelsea deal. This season has been awful," the midfielder acknowledged.
"Everything points to me changing the environment after five years, but we'll have to wait and see."
