I think we may have missed the boat on Schneiderlin sadly. I can see us going for him again, but can also see our rivals trying for him simply to stop us getting him. Who would people want as an alternative?
What worries is that it's not just individual mistakes or bad positional play that has cost, it's pretty much everything:
We can't defend from set pieces. Players have free headers and even when they are marked, often the player marking him does not jump with him or put much of an effort in to stop him. We rarely even have players marking the posts! Such a basic thing that a lot of teams don't do these days, Carrick's goal for example could have been avoided had there been a defender on the line.
Gutless play from the likes of Vertonghen who is unwilling to put his body on the line where there is even the slightest chance he COULD get hurt.
Poor positional play from the likes of Walker.
Basic errors from practically all of the defenders at times.
I think you are being a little over the top, but to clarify on the it's everything
- We rely on our two heavily attacking FB's which often leaves a space for the opposition. Teams have taken advantage of that in the past by simply hitting a ball over the top to a runner and that leaves the two CB's badly exposed.
- This is made worse by the fact that we don't play a dedicated DM/destroyer (not saying its a must, but contributes to the challenge), due to that, when we lose the ball, deep lying midfielders/defenders in the opposition have enough time to make a long ball pass to that runner.
- Finally, out of all of our CBs, only Fazio is any particularly any good in the air, so once he's out of the side, having no CB to cut out some of those punts again furthers the issue. Lack of a dominant defender in the air also hurts in set piece issues.
Said it before in this and other threads, in preseason it was clear strategy for the FB's to go forward, but a dedicated CM fell back into the space to cover (Mason did a lot in preseason), it's something I very rarely have seen in actual PL games.
To me, Kaboul/Vlad simply don't have the qualities to be significant for us.
Fazio is needs to be part of our setup regularly, or we need a replacement who is good in air
The midfield has to help cover for our suicidal FB style/model
We are badly dependent on an in form Walker, him injured or out of form is a major problem, Poch needs to figure out if the yank will work, or get cover/challenger
