I don't particularly agree with that.
There's been quite a lot of games last/this season that looked lost causes to then be suddenly swung in our favour (Spurs away, Wolves away, West Ham home, Fulham away, Betis for example) and he's also shown in recent weeks that he's prepared to go defensive/park the bus to see a game through (Liverpool, Forest) although ofcourse that remains to be seen if that was just a temporary measure to make sure we hit our targets at crunch time.
