Kovacic has spent the season with Chelsea on loan from Real Madrid.
Chelsea manager Maurizio Sarri has confessed he would love the club to secure the permanent signing of Real Madrid midfielder Mateo Kovacic.
Kovacic moved to Stamford Bridge on loan last summer as part of the deal which took Thibaut Courtois to Real, and the 24-year-old has been a regular part of Sarri's lineup this season.
He said: “Yes, Kovacic is only on loan, of course. I'd like very much that Kovacic will stay with us. You know very well that, in that position, we have some problems because we have only Jorginho.
"In my opinion, Kovacic could become a very good central midfielder. Of course, he is not a defensive midfielder but, as you know, in that position I prefer a very technical player. In the last match, Jorginho touched 161 balls.
"So, for us, it's very important for us to have big quality in that position. Big quality not for the last pass, but big quality in terms of moving the ball. No [I don't want to buy another midfielder], I want to try with Kovacic.”
Kovacic has made 42 appearances for Chelsea this season, often rotating starting duties with Ross Barkley. Many fans have praised his ability to help advance play, but there are those who have also grown frustrated at his lack of impact in front of goal.
He is yet to score this season, just as he failed to score for Real last season. His last goal in club football came in January 2017 during a 3-0 victory over Real Sociedad, while he has managed just 18 goals in his 311 senior appearances throughout his career.
A large part of the Stamford Bridge faithful have called for Loftus-Cheek to be given the chances in the first team, largely due to his greater goal threat. The 23-year-old has eight goals and three assists to his name this season, but has started just two Premier League matches this season.
