I played competitive team sports to a moderately high level and if that qualifies me to throw my opinion in, I don't know. However what I am seeing is listlessness. What I mean is that we do not have a general right now. There is no fulcrum for our play or our attack. Mata is trying, but he is gun shy. He's very skillful, but he is typically unwilling to try to force something if it requires physicality.
Schweinsteiger is trying to be the general, but his position as field boss is undermined by the fact he is a new-comer and he doesn't have the captains armband.
Whether or not Rooney is past it remains to be seen. There are too many failures and break downs right now in our attacking play to definitively say Rooney is the problem. I honestly don't think his misses today were really that big of a deal. None of them were egregious, they were all extremely difficult chances to take.
Depay is supposed to be "the guy", but so far and I think it's safe to say he has consistently been our worst player in the regular starting XI so far. Too young? Too soon? Too many problems for him to be reasonably expected to have an impact? I think youth is probably the issue here. His decision making is what is failing him. He is making consistently bad choices and trying to force the issue (which is what Mata could use tbh)
Our attack is a mess. Rooney is not getting quality service. If you watch our attacking movements and compare them to Swansea, we're not attacking in depth. Rooney is being isolated. We're basically failing to move the ball consistently forward with numbers. We're left stretching to make a move in that final 1/4th of the pitch. This isn't really anything new, the tactics being played against us that is.
Teams play defensively and look to hit us on the break. The issue is, we're not finding much success in breaking teams down when they are looking to defend and break.
LvG needs to officially deputize Schweinsteiger. Give him the armband. Let him direct traffic. Mata needs to be moved centrally. Depay needs to be sat and brought on as an impact player around 55-60m until he gets his confidence/groove. We need to sort our issues from the back to the front. If we start creating consistent threatening penetrating play and Rooney is shitting the bed, then we need to worry about him.
