I liked Kovacic a lot, he was one of the players for who I felt more sympathy.
I was a bit disappointed when he went on loan, the coldness with Madrid, assuming he wouldn't return, as if he wanted to erase those years.
It is never positive to say of a player "he will be the new X". That happened with Modric.
It resulted in a strange situation of assured bench and a supposed growth and brilliant future.
Perhaps, watching the competition, he said that his best position was holding midfielder. In that position came his most famous match, a great mark to Messi.
After that he returned for months to disappear.
Apparently he considers that his time in the bench provoked his time in the bench during the world cup.
I do not know if he has regained his place in the team. I do not know Brozovic but he is definitely not better than Rakitic.
I wish him good luck, he looks like a great guy that is looking forward of playing and being a true part of a team
