Disagree with this. Getting 1 lucky shot on target in the second half is not a performance we'd sing Rafa's praises for. Especially against a side as poor as Crystal Palace were today. Praise was lavished on Rafa when we got 1-0 wins against better sides, whilst clearly playing a plan/system well. Give it 6 months and the luck will even out.
Also, imagine what Rafa would have done with the money Bruce got and against the poor oppositions we have faced this season.
