I always said we should of signed Bale, from day one when everyone was saying he is overrated and inconsistent. Players like Bale probably won't turn it on every game, but you will get a good 10-15 wins out of them because a player like him is a match winner. Class.
If your looking at other targets i would say...
Marco Reus- Offer us width, pace and possibly goals
Iker Munian- Wouldn't say he is an out an out winger, but he is the type of player we need. Determined, fast, skilful and very technically gifted with good creative abilities.
Isco- Hardly a winger also, but can offer us pace still and is also a very good technician.
Mario Gotze- Pretty much same as the previous 2 i mentioned, but can adapt to a wide role, plus giving us more creativity in the side.
Alexis Sanchez- Maybe not done it at Barca, but he is a very skilful player with power and is also very very fast. Something City have lacked for the past 2 seasons. Pace out on the wings is essential.
Jesus Navas- Excellent crosser of a ball and would offer us a lot of width, doubt he would come due to being homesick.
Stevan Jovetic- Another one of those players who is not an out an out winger, but we could use him as an inside forward, very good player who is the type of character we need in our side. Very determined with a good football brain.
As someone has already mentioned, Valbuena would possibly be a shrewd signing, probably would not cost a lot but he would offer us pace and does seem to be a very hard working player, unlike Nasri who can be a lazy bastard. I personally think we should of signed Lucas Moura when we had the chance, unbelievably quick and could of only got better. Would of been a handful in the Premier League. Would be scary.
People who are saying Di Maria are being very very unrealistic. From Real Madrid to Manchester City... come off it. Cuckoo land.
