He wasn't anyone's dream-signing, but it is ridiculous to see people in here say that they always rated Kovacic, and that RM is so much smarter than us by getting him.
Kovacic was heavily criticized last year and many RM-fans was saying exactly the same as we are with Gomes now: It is not even worth the wait for him to adapt, he is just not a right fit etc.. Gomes also need time to adapt, but of course someone like Gundogan presumably would have adapted faster.
Maybe Gomes will never work, but it is kind of dumb to rule him out after 10-15 games, and especially using a comparison with a player (Kovacic) who went through the exact same thing and only turned out good after more than a year.
