As B&S has alluded to elsewhere it will be very interesting to see what team he puts out on Saturday on the back of 2 improved, backs to the wall, defensive away games with a lone forward. Will he go with the same which would be pretty negative for a home game or will he change it again?
Do you mean the style of play used the last two games or playing 1 up front being negative (or both)?
There is nothing negative about playing 1 up front as long as the team's general style is positive and the 2 attacking midfielders behind the striker (and to some extent the wing-backs) are given enough freedom. That's often more attacking than a standard 3-5-2 IMO
