Looking at the best, worst and likely outcomes of this season:
Best: 4th spot, FA cup winners.
Worst: 5th spot (I know 6th is mathmatically still possible but highly unlikely now), FA cup runners up
Likely: 5th spot and FA cup winners.
Looking at the season upon reflection you have to say that even the worst outcome is progress from when LVG took over. Maybe we're being a little harsh?
It only seems like progress because Moyes made such a mess of things in first place. There was no way the squad we had in 13/14 should have finished 7th, it should have been top four at the very worst. Even if you accept that Ferguson got the team to punch above it's weight the previous year, we had the league's best player on our books and a wealth of experienced internationals who had won titles before. What van Gaal did last season was return us what should be considered the bare minimum standard (ie. top four without a trophy) and all whilst getting rid of a bunch of players and spending significantly. For that reason, he was allowed to carry on in what should have been a continued upward trajectory.
This season we should have been challenging for the league, no question about it. You say the Premier League is more competitive, but the standard is lowest I can remember ever seeing (no disrespect meant to the worthy winners, Leicester). Our best teams, Arsenal's 03/04 side, City's best, Mourinho's first Chelsea team and probably that Liverpool team with Suarez would win the league this season without breaking a sweat, I'm confident of that. Instead, we're just about clinging on to top four and although we might win our first major trophy since Ferguson left, the style of play has been absolutely woeful the vast majority of the time and hasn't improved whatsoever since he first stepped through the door. In fact, it's gone backwards if anything in the second season. We're on course to finish with our worst total number of goals scored in the Premier League and it's not even close and we've been embarrassed in several games in domestic and European competition (MK Dons, 'Boro, Champions League group stage, Midtjylland etc.). It's not good enough for a club of our size and stature and he has to go this summer.
