Mauricio Pochettino has been warned against letting Mateo Kovacic leave Chelsea in the summer transfer window - but has been told Kai Havertz should be sold. The Blues are set to move on a number of senior players with the Croatian entering the final year of his contract at Stamford Bridge.
Kovacic returned from injury in the final game of the Premier League season as Frank Lampard ended his spell as caretaker boss with a 1-1 draw against Newcastle. The 29-year-old has endured a number of injury problems this season and now looks set to have made his last appearances for the Blues.
The Croatia international has enjoyed a successful five-year spell at Stamford Bridge, winning the Champions League, Europa League, UEFA Super Cup and FIFA Club World Cup. According to Fabrizio Romano, positive discussions have taken place between Manchester City and Kovacic's camp this month over personal terms.
