My biggest worry is we're too predictable. We're not flexible and we don't have different options about how we are going to set up.
I'm not sure we have the players to play the formation Rafa wants. We still concede goals with this formation, it's not like we look super secure at the back.
We have pace on the wings, and strikers who can head a ball. We've never seen the big man/little man partnership of Mitro/Gayle at all.
Rafa clearly has a very valid point with Snide Ashley and the lack of investment, but IMO we're not playing to the strengths of the squad we have.
4-4-2 (especially at home) would work a lot better IMO.
