I have to admit to knowing very little about him, apart from cursing him when he scored against us. I couldn't even tell you what sort of midfielder he's supposed to be? Is he a potential partner for Kamara at the base of midfield? Or someone to play further forward in Youri's role? Or could he be a more defensive-minded left/right sided midfielder like McGinn? Maybe he can do all of the above?
I'm always happy to see technically competent midfielders join our ranks, and his age is a bonus. If we add him and Manazambi, that'll do wonders for the age profile of our side, but I'm not sure it makes our first team "stronger" to add those two while losing Youri and Onana? (only because I don't know the new two as well as Youri and Onana, that's not a judgement on their replacements, it's a question)
