It's a question of balance between the manager rebuilding the playing side with an empty wallet whilst getting the best from the squad he has acquired or inherited. As rA says there's no Igor on the horizon so we are where we are!
The impression being given by Rosenior is that his lack of knowledge beyond the PL is so limited that he is being asked the question 'if my methods aren't working can I adapt to the needs of L1 to achieve success? '!
He says he is going to make changes so he needs to be given a little longer but if we can't beat Wycombe then questions will be asked. Each game after that will see the screw tightening and if the poor results (and lack of goals) continue I don't see him lasting beyond mid October!
