Jurgen Klopp insists he is not "too loyal" to his "underperforming" senior players and says Liverpool will only look to bolster their squad in January if deals are "available and doable".

Klopp has a number of problems to solve after admitting Saturday's 3-0 loss to Brighton was the worst performance of his managerial career.

His side have already lost six times in the Premier League - after being beaten only four times in 63 games in all competitions last season - and are 10 points adrift of the top four.

Speaking on the eve of Liverpool's FA Cup third-round replay with Wolves Klopp said the issues at Liverpool are "complex" and cannot be resolved by simply spending in the transfer window, despite admitting the need to strengthen - Liverpool have already spent up to £45m on the signing of Cody Gakpo this January.

Under particular scrutiny has been Liverpool's ageing midfield with captain Jordan Henderson himself admitting Saturday's defeat at Brighton "lacked energy".

Henderson (32) and Fabinho (29) - who have won every club trophy during their time at Anfield - and 31-year-old Thiago, a later arrival but still a double cup winner last season, remain the Reds' first-choice midfield.

Staving off criticism he is overly-reliant on the so-called old guard, Klopp said: "I heard I'm too loyal but I am not too loyal. The problem is too complex. If you can then go out and bring in another player to replace him, then it makes sense.

"But if you cannot bring anyone in, you cannot take anyone out. I am not too loyal. At Dortmund before I left, I said something had to change here - either a management change or a lot of other things needed to change.

"I will be here for as long as I am wanted. If no one tells me to go, I will not go. It is something for the future, in the summer, not now. The only thing I want is to fix this situation - that is all.

"It is clear that there will be an important period of change. There have been injuries, but no one is interested in that. The boys feel the responsibility, but we're sticking together with all we have."

He added: "Do we have to strengthen? Oh yes. But is this the right moment for it? I cannot see it because of the situation we are in, I think I know exactly how that is, and that's it. I cannot change the answer every week. Even when we lost another game since the last press conference, it doesn't change."
