Alongside Eden Hazard, Mateo Kovacic was one of Chelsea’s players who returned to London extremely late from the World Cup.
Although he wasn’t a regular starter for Croatia, he helped play a part in their run to the final.
So the fact that he was able to come in almost immediately and perform at a high standard is credit to his ability.
However, Kovacic’s easiness on the eye cannot obscure the fact that he lacks an end product from midfield.
He’s yet to score for the Blues and has provided only one assist in all competitions.
If this was to happen, it would be bad news for Chelsea’s most promising player, Mason Mount.
Mount came through Chelsea’s academy and went to Derby County on loan to play under Blues legend Frank Lampard.
And the England midfielder has got five goals and one assist already, despite being injured for the last few weeks.
Chelsea fans everywhere are hoping Mount returns to Stamford Bridge to play next season.
And signing Kovacic would suggest Mount may struggle for playing time, and therefore should be avoided at all costs.
