We've spent most of the season locked in a top four position, and while I know we've had some key injuries/absences at unfortunate times, there's also been a lot of times where we just haven't looked up for certain games. Go back 4 months or so & top four looks like a certainty while the title looks like an impossibility, so maybe he allowed the team to get somewhat complacent?
Can't blame it all on Lallana/Mane being AWOL. We know the AFCON is a thing, so Klopp either had to adjust or bring in a player in Jan - He did neither, and while the latter might not have been his fault, now what looked like a sure thing is going to be a battle to the last day.
At the start of the season, I would've looked at a 5th to 3rd finish as a solid season, as there's (at least) four teams with better squads than us in the league. But to go from what looked like a guaranteed top four spot a few months back to potentially another Europa league season... Meh.
