Mateo Kovacic joined Chelsea on a season-long deal as part of a move that saw former Blues goalkeeper Thibaut Courtois leave Chelsea for Real Madrid.
The Croatian has been a very important player for Chelsea this season and has been involved in 41 games this season, but is yet to score a goal for the Blues, and his impact for the side has been dropping as the season is nearing its end.
Chelsea legend Jimmy Floyd-Hasselbaink has told Chelsea not to sign the 24-year-old at the end of the season but rather let him return to his parent club.
Hasselbaink believes that Kovacic won’t add anything to the squad next season and the Blues need a more creative midfielder who can split defences with a final pass and aid strikers with an assist.
“I don’t think Chelsea should pursue Kovacic,” Hasselbaink told Bwin.
“I think he was signed as a way to get better value from the deal that saw Courtois go to Real Madrid, but he hasn’t been used correctly at Chelsea.
“Kovacic is a defensive midfielder and that is where he performed best at Real Madrid, but Chelsea are already blessed with Jorginho and Kante in that role.
“Chelsea need a midfielder who has creativity and can split defences with a final pass, who can set up strikers and achieve assists, but this is not Kovacic’s strengths.”
Although Kovacic is yet to score his first goal for Chelsea, Sarri has been impressed with the 24-year-old and has admitted he wants the club to sign him on a permanent deal.
When asked whether he wanted to enter the market for another midfielder this summer, as Chelsea attempt to overturn a two-window transfer ban when their appeal is heard by FIFA this Thursday, Sarri said: “No, I want to try with Kovacic.
“He is only on loan, of course, but 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 (at the moment) 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.”
