He won't become any better, but his reputation might still change a lot. It already did just in the last months, because he played decently in a few games in Barcelona whereas he was struggling at Wolves.
His game is simple but can be hard to defend against. With the right role in the right team he can be successful. It was the same with the american Konrad who would've been free to keep. There are more players like that too, although none with the same biceps probably.
This thread is about Depay however, and he was back to shit last game, there is really nothing good to be said about him as a player. He had a couple of slightly better sub-ons lately after the injury, looking a bit fresher and failing a bit less, but last game he was back to his habitual state.
