It's all a bit patronsing with this "what more do they expect". It's like everyone outside of the top six should just be grateful to be in the Premier League and accept mid table mediocrity. Heaven help a club should actually have a bit of ambition and try to break into the top 4/6, hard as it will be.
We recently finished 5th, we've been the best equipped club (allowing for Leicester's freak season) to break in to the top 6 in recent season, we've just finished 5 points below the mighty Burnley who went something like 12 games without a win at one point and Arsenal have had one of their worst seasons in a generation and we still didn't capitalise on it. So I think we're perfectly entitled to feel that we might just have missed a trick this year and it's fair to have expected a bit more than Allardyce offered for the last few months.
