I think we do have a clear system under Johnson. His preferred formation is clearly the 4-2-2-2 that we've seen so much of. The good thing about him, though, is that he's not wedded to one formation or one approach. As he's said himself, he picks the team and the formation based on the opposition. That's the basis of good football management. One defeat doesn't mean that he needs to change that approach. Even Fergie used to do that. You can't just pick the same 11 in the same formation week in, week out anymore. You'll be worked out very quickly if you do that.
