So far, it doesn't look like it was wise to sign him and loan Januzaj. Both are pretty much at the same level, around the same stage of development, and while both are very talented, both are as inconsistent as they can be and their decision making is absolutely horrible. Like, really horrible when 4 out of 5 times they choose the completely wrong option.
To be fair, I was expecting an upgrade on Adnan, but it hasn't been the case at all. What we have seen so far is a stronger version of Adnan with significantly worse passing.
Anyway, it is still too early in his career and while I wasn't expecting a world beater, I thought that he'll do better. His true worth will be shown next season. But, I think that benching him for a few games is the right solution. It is already difficult playing with a passenger in the team (that would be our captain), but with two it really becomes very difficult.
