I actually agree with alot of that, I've been wanting Giacc instead of Gomez for a while now. However, I don't think it's the system that doesn't support the striker scoring goals, I actually think it's the personnel that's the problem.
Gus is constantly trying to get players to play higher, but our defenders are too slow to maintain such a high line. Don't get me wrong, I love JOS & Wes, but they drag the whole team back when they try to compensate for their lack of pace. Add to that our patchwork situation at fullback due to injury, and our inability to string a couple of passes together then isolation of the striker becomes inevitable.
We have seen the system work if we have the right players, but that will take more time.
