This season, but in 2021 they won the CL :). He has been excellent for Croatia this season, for example.You don't play for Inter, Real & Chelsea (ok maybe not Chelsea) and get capped almost 100 times by Croatia without being at least a semi-useful midfielder. Would be a good addition to the squad if we can get him for a decent fee.
We have been interested in Kovacic since 2013, he is one of those players with a very high ceiling ability-wise, and you just know that the guy needs someone like Pep to help him fulfill his potential.
For anyone interested, it's Netherlands vs Croatia tonight, a chance to see him in action.
