Mateo Kovacic could find himself reunited with former boss Thomas Tuchel this summer, with Mauricio Pochettino having reportedly picked out a No 6 as his priority this summer.
The former Tottenham and PSG boss has been heavily linked with the vacant managerial role at the Blues, after Graham Potter was sacked after just seven months in charge.
As a result, he has been quick to outline his plans for where Chelsea can strengthen in the summer, according to Metro, should he be named manager, with a deeper-lying midfielder top of his list.
