Liverpool manager Jurgen Klopp returned to work less than 48 hours after having his appendix removed and immediately set about trying to cure some of the club's own ailments.

The German missed Saturday's 2-2 draw with Sunderland after being rushed to hospital for an operation and so did not witness the 77th-minute walkout of fans protesting at the rise in ticket prices next season.

Klopp was prevented from answering questions on the matter in his press conference ahead of the match, but, having discovered what happened at Anfield at the weekend, he waded straight into the row.

Moves are already afoot within the club's hierarchy - who cancelled Monday night's question and answer session with chief executive Ian Ayre on their own television channel - to consider reviewing the ticket pricing structure.

And, with Klopp speaking publicly on the subject for the first time, it seems further developments are likely.

"When I heard about it (the walkout) I was disappointed," said the Reds boss.

"I've had a lot of things to do in the last few weeks, but now I know it is my problem too of course

"But everything I could say about this now would make it more complicated, because first of all I have to collect a few bits of information.

"What I know is everyone in the club has a big interest in finding a solution for this.

"We don't want the people leaving the stadium before the game is finished."

Klopp will be back in the technical area for their FA Cup fourth-round replay at West Ham on Tuesday night.

It may not be the normal, effusive and ebullient German the Premier League has already become accustomed to seeing on the touchline, but he insists he is fighting fit after surgery.

"I think I am experienced to know that for me it is not a normal coaching game so I won't be jumping about," he added.

"I can't win the game with my emotions outside, I know this, so I can handle it no worries.

"But I feel good and I am back in the race. Everything is okay and we don't have to talk about this any more."

Klopp will hope to have strikers Daniel Sturridge, Divock Origi and playmaker Philippe Coutinho available for selection at Upton Park.

He will, however, continue to rest players he believes are in need of a rest after a hectic January so the likes of Steven Caulker, Brad Smith, Kevin Stewart and Joao Teixeira are likely to get a run out alongside more regular first-teamers like Christian Benteke.
