It could also help N'Zogbia as he likes playing on the right wing and not the left. Brahimi judging by youtube was played on the left wing a lot so not only does Brahimi speak French so N'Zogbia will have a friend, but N'Zogbia may get to finally play where he wants.
The issue last season is McLeish had his own way Gabby on the wing, N'Zogbia on the left when he wanted to be on the right, Ireland on the wing at times when he wanted to be in the middle.. It's not hard to keep players happy and provided they put in a shift where they want to be played then it works.. Managers need to listen to their players as much as they listen to their staff, McLeish didn't listen to the players.
