There's always one or two positions that seems to be cursed. Right now half the pitch is cursed though, so I guess that's an improvement curse-wise...
The rightback position never really recovered after G.Neville's prime. The right wing has also been largely shit after Ronaldo left for Madrid, although Valencia had a very good season there. I guess our entire right flank got cursed after the luxury of Neville, Beckham and Ronaldo.
Our central midfield has been in an even more sorry state, though. The only truly great central midfielder(not counting attacking midfielders) from the last 10 years has been Carrick, which is pretty shocking to say the least.
