Are you serious?
In this system our full backs have no cover whatsoever. The wide midfielders/attackers (for the last half hour they were in fact BWP and McG - 2 alleged strikers) do not know whether to get back or not. The point was in fact made by the sky commentator.
The 2 midfielders cannot get over to support otherwise we get overrun in the middle of the park.
The best 2 full backs in the world would have a tough time with no cover. Lloyd James is never going to be the next Cafu but he is so exposed he looks worse than he is.
Further up the pitch the widemen looked awful and the rest of the team completely disjointed. We looked a whole lot better when we went 424, or whatever it was, following the subs. We had 2 "normal" strikers and 2 "normal" CM players and looked much better.
If we went 442 it would give cover to the fullbacks, give us more strength and options up front where we are plainly lacking.
Based on the last half hour, and assuming Schneiderlin is still crocked, we have 2 of Gillett, Surman (those 2 would be choice), Cork, Wotton and James (before you laugh I have seen him play loads of times at CM paired with Gillett and they play really well together). The wide berths could be filled by Lallana, Smith, Surman orThomson. I know we have loads of centre forwards with recent expereience as wingers but I prefer to see round pegs in round holes.
I have never really been a believer that systems make much difference but having seen us get battered down the flanks and look gash up front most of the season it is bloody obvious to me that this system is not the best for us.
