Jurgen Klopp is confident that Mohamed Salah will sign a new contract with Liverpool amid speculation around the forward's future.

Salah, who is currently on international duty with Egypt at the Africa Cup of Nations, recently gave an interview to GQ in which he stated he is not asking for "crazy" money during negotiations, adding that he wants to stay but that the decision rests with the club.

Speaking at a news conference ahead of Thursday's EFL Cup semi-final first leg against Arsenal, Klopp was asked about Salah's interview and whether he was at all worried the star might not re-sign, with just 18 months remaining on his current deal at Anfield.

"I know that Mo wants to stay. We want Mo to stay. That's where we are," Klopp told reporters. "These things take time. I think it is in a good place. I'm very positive about it.

"There is nothing to worry about, it is a normal process. He has a contract here for this season and next season. It is all fine."

Klopp was also asked about his comments after the win against Shrewsbury Town in the FA Cup third round on Sunday that his players had returned "false positive" COVID-19 tests, which led to the first leg of the tie with Arsenal that had been scheduled to be played last week being postponed.

Liverpool requested that the game at the Emirates Stadium be pushed back by two weeks due to a COVID-19 outbreak at the club that led to the training ground being closed for 48 hours.

But the German coach seemed to suggest many of those cases turned out to be false positives, with only Trent Alexander-Arnold returning another positive after re-testing.

"You get a positive test, then when you do a re-test a day, day and a half later, you get a result that makes it seem like a false positive because this test was negative," he clarified. 

"That doesn't change anything for your quarantine or whatever but if you need to know, you have to do a third test.

"Between the first and second, and second and third test you cannot use the players, so that's how the rules are.

"If you get a third test and that's negative as well, then that's it. It was now four days later, so we couldn't do anything different. When we got the positive tests, we had to consider that this was the right result."

Klopp confirmed that Alexander-Arnold is back in training along with Alisson, but Thiago Alcantara and Divock Origi remain sidelined by injury.

He also had a positive update on the status of Harvey Elliott, who has not played since suffering a fractured ankle in the 3-0 win at Leeds United in September.

"Harvey Elliott looks really promising out on the pitch now," said the Reds boss. "He didn't train with the team yet, but I don't think he's too far away from team training.

"What he's doing at the moment looks really good."
