Against Sheffield we started off with a 4-3-3 then transitioned into 4-2-3-1 when Pepe came on. Willian in the hole was so much more useful than on the flanks.
Regardless of what formation we play, the team shape is mostly the same when defending deep or in full attack. It's how we transition that changes. I don't really like the 4-3-3 we put up 1st half, it was neither here nor there.
In defence, I'm a little worried that we love ceding the wide areas to shore up the box, especially late in games. I don't think it works. It affords opponents a lot of little chances which eventually add up.
In attack we have this really Wengerish habit of trying to craft the perfect strike.
A lot of tactics talk this thread, maybe we need a new tactics thread?
