We need more than one player. We have 3 established centre backs - one decent (Jones, contrary to Hoppity's ignorant opinion) and two average (Smalling and Evans), plus a bunch of kids. Not the recipe for a successful back 3, at least not any time soon. Wing is another problem area. Shaw, Januzaj, and Valencia are decent. Young and Nani are shit. Lingard I haven't seen enough of. Van Gaal seems the type to play a long game though. The United fans slitting their wrists after one game can go follow City.
At the moment we don't play wingers, but if we were going to Januzaj is our only good one. Young is not a good winger, but to give him credit he is doing alright as a wing back. The prob vs Swansea was he was asked to play fullback, which he clearly isn't.
Lingard is a very good forward, but he plays as an attacking winger/number 10/forward. Not sure why he was a wing back. James as left back and Young on the right would be better.
The first choice back 3 are all very good, but are injury prone. The kids are very capable. We do need another body back there though.
A new mid is a must, it is so slow.
A winger would be nice if we were to go back to 443 but not as urgent if we play 343.
Mata needs to wake up, and Herrera will need a few weeks to learn what the prem is all about. Hopefully he will justify the price tag.
