I wouldn't say we got 5th by luck. What I would say is that relied too much on individual moments of brilliance from Berbs and Keane primarily.
I understand most people would not like to even consider our achievements as being partially due to luck. But when I look in retrospect at the other teams we were competing with for UEFA places last year it's pretty obvious we should have had 5th spot covered at half-season - I mean Pompey, Everton, Blackburn, Bolton, etc.??? These are the teams we barely managed to overtake at the end (and in the case of Bolton it was mostly due to Big Sam resigning).
5th sounds very good - but it's all relative and, like it's already showing this year, when there're more reasonable teams apart from the top 4 we can't deliver.
Realistically, if we had a separate league now with only us, Newcastle, Everton, Man City, Pompey in it where would we finish? These teams have consistently improved and we've only gotten worse.
