We need to get away from the idea that Koeman was left a mess. He really wasn't. He was left a squad which needed a few quality additions and some good coaching to get up sniffing around the top 4/5. Unfortunately there has been little to suggest that we've had either of those things so far.
I would say two consecutive bottom half league finishes for the first time in 14 years, culminating in the worst home record in a single season in the club's entire 138 year history was 'a mess'.
The whole squad is totally overrated. We got told frequently last season it was the 'best squad we've had in 25 years'. Absolute horse manure. We have one half decent striker (Lukaku) who scores goals when he's motivated (not all the time), who cannot play up front on his own, hold the ball up, play as a lone striker and who does a fraction of the running that the best strikers in the division do.
We have a centre half in his 30s who is finished (Jags), another who has seen better days (Williams), and a full back who is still useful but the wrong side of 30 (Baines). In midfield we have a 35 year old who we rely on to play every game in order to make the midfield sort of acceptable (Barry). That's four 30+ year olds who are considered key members of the first team. It's embarrassing.
We have no back up strikers who are any good. We have a young talent in Barkley who seemed to peak about 3 years ago aged 20 and has not kicked on, criticised by multiple managers and people in the game, so not just one person's opinion.
As for the rest, there's the invisible man Mirallas, Deulofeu who is yet to have a good performance for a full 90 minutes, washed up people like Aaron Lennon, Darron Gibson, James McCarthy and loads more.
The squad needs to be totally ripped to pieces and be reconstructed.
Here's an example from history. This is the line up from Kendall's first game in charge as manager in 1981, many of the team players he inherited from Gordon Lee:
Jim Arnold
John Bailey
Billy Wright
Mick Lyons
Mick Walsh
Alan Ainscow
Asa Hartford
Trevor Ross
Mickey Thomas
Alan Biley
Peter Eastoe
Fast forward to the 1984-1987 glory years - only Bailey out of that 11 survived, and even he was soon gone, replaced by Pat Van Den Hauwe in the starting line up for most of the 84/85 season.
That's the type of wholesale change needed under Koeman, and it's going to take time.
People need to stop making excuses for the players. They're rubbish and they don't care. Get rid of most of them and start again.
