Perez should start here in the right flank! That kid Iwobi must be dropped from first team! He has horrible stats for a forward and having scored 1 goal with so many games at home and even CL he shouldn't be near first team! Wenger is a right idiot! Start Ramsey with Xhaka in the middle as Arsenal'd have better ball movement in the and Perez on end tight flank! Arsenal 3:0!
The role of the trainer is also to turn not so good players into great players. Or there wouldn't have any newcomer into the football. If he knows that Iwobi has some potential, giving a try won't cost him too much. I think he can say goodbye to the Premier League title, so he only needs to get qualified for next year's Champions League by being ranked 1, 2, 3, 4 or 5. He also has to prepare for the match against Bayern Munich, so better use young talents now so they can be used for this great match to come.
