Manchester United manager, Ralf Rangnick has revealed his ‘biggest disappointment’ at the club as he walks away from his managerial duties.

The time of the German interim manager in charge of the club ends on Sunday after their last Premier League game of the season against Crystal Palace.

Rangnick was called in six months ago to replace sacked Ole Gunnar Solskjaer in a six-month deal that runs out in June.

The German did not make any tangible progress as the club was eighth when Solskjaer left and is either finishing sixth or seventh, failing to qualify for next season’s Champions League.

The period he spent managing the club has generally been viewed as a failure and he was asked to identify his ‘biggest disappointment’ at his final pre-match press conference on Friday afternoon.

“Since Atletico, we just didn’t find our shape or form again,” he said.

“Before then we had stabilised the team, become more stable defensively. But then we lost confidence and energy.

“It has got to do with confidence, team spirit and togetherness. This is my biggest disappointment that we didn’t establish that team spirit.

“I still strongly believe that there is a core of players here who are top, good enough to play for this club.”
