From Jose Mourinho's ouster, followed by a brief magical spell under Ole Gunnar Solskjaer, and then going back to the woeful form, United failed to secure a UCL berth this term.
While critics have once again questioned Solskjaer's tactics, the man himself reveals as to what went wrong with the club last season.
Mental tiredness behind an under-performing season
Solskjaer admitted that the side failed to cope up with the ups and downs last season, which defined their season.
He also reasoned that owing to the mental tiredness in what was a draining season, it all went wrong for them.
"But, we will be better this year. We need to improve and we need to be better," Solskjaer said to talkSPORT.
I can see us improving a lot: Solskjaer
"The more we improve and the more we get better, the bigger the chance we can challenge for trophies at the end of the season. These boys have shown their capabilities. If we just stay level-headed, I can see us improving a lot," added Solskjaer.
Difficult for a new manager to take charge: Solskjaer
Solskjaer revealed that it is always difficult for a new manager to take charge especially mid-season, following the sacking of the former manager.
However, Solskjaer praised the players for having come back strong, fit and sharp.
"I know how fine the margins are in football and how easily things can go from good to bad. It is a mental game," continued Solskjaer.
