Valencia and Young are awful and overrated. Both were beyond useless last season, and even the season before were barely special.
Zaha was immensely overrated for Crystal Palace of all teams last season, I will be surprised if he makes an impact at all this season and even if he does it'll be in the second half surely. He is not good enough yet, we were the other club linked to him and I didn't want us to get him, especially at ?15 m.
Giggs isn't a winger any more.
Nani is your best winger IMO but still hugely inconsistent and selfish, he is barely good enough for Man Utd tbh. In terms of players who can play on the wings though, Kagawa could do a job there if he is given more time to settle and get into the team. He is no winger but he is better than the rest of the hacks.
With Di Maria supposedly on the move, he'd be a brilliant signing. He'd take Man Utd over Spurs any day which looks another possible destination if Spurs sell Bale.
I think in Man Utd's system a CM isn't vitally important, it would help, but as we saw they can still win the title with Carrick and a few others like Cleverley and the embarrassingly bad Anderson.
The GK spot is finally looking solid, as is van Persie as a striker. Carrick was good as well and Rafael has really improved. Other than that, there is plenty of room for improvement elsewhere. I think in terms of depth the squad is really good which helped in the last two seasons but the starting options aren't quite good enough which stops United from winning the CL more than the PL.
Man City aren't sure fire for the PL, but Chelsea still haven't improved a whole lot from last season and Man Utd still have the seem deficiencies. So I think with a better manager and some decent new signings they will look good. Their absolutely brilliant squad really helps.
I am confident even if Chelsea don't sign a striker, Lukaku will do the job. Torres and Ba are decent back-ups as well, I hope Lukaku actually starts most of the time.
I think if we sign Suarez we will be in there, even if we don't (which is more likely) we will get to around 2nd or 3rd. Since we won our last trophy, we've challenged for the title every season except for seasons where we've lost big players. This season will be no different.
