Liverpool manager Jurgen Klopp has revealed that Alberto Moreno will miss his side's clash against Everton on Sunday [10 December] and could be out for up to a fortnight after suffering an injury during his side's 7-0 drubbing of Spartak Moscow on Wednesday.

Moreno, who has enjoyed something of a renaissance at Anfield after looking destined to leave in the summer, seemed to twist his ankle when stretching to clear a low ball in the penalty area against Spartak and looked in some discomfort as he trudged down the tunnel just before half-time.

Klopp said immediately after the match against Spartak that Moreno's injury looked minor and hoped that a stroke of luck could see the Spaniard feature against Everton, but the former Borussia Dortmund boss revealed on Friday that the Liverpool star's injury is still unknown, with further tests scheduled to determine the extent of the knock.

"We're not sure what it is yet. It's around the tendon," Klopp said in his press conference. "We have to make further assessment. It could be one week or it could be a couple of weeks."

Moreno will miss the clash against Everton, who have shown signs of life after comfortably winning their last three matches, but Liverpool captain Jordan Henderson will be involved in the 229th edition of the Merseyside derby.

Much was made of Henderson's omission from the starting line-up against Spartak, but Klopp, who mentioned Everton manager Sam Allardyce's decision to "make 15 changes" for the Europa League clash with Apollon Limassol more than once, revealed his decision to bench his skipper was simply down to his rotation policy, and expressed his anger over the speculation that predictably followed.

"Even the captain cannot play all the time, that's how it is," Klopp said. "He's in a good moment in good shape but I made a decision for Spartak, we need players at 100% in a derby.

"I said he would play against Everton because I knew people would try and make a s**t story out of it. They are s**t stories. He is such an important player for us and I don't get why I have to explain this. Being the skipper at Liverpool is the hardest job in world football because the man before was Steven Gerrard. I want everyone to respect him, there's no story."
