Henderson's difficulty could be Thiago's chance

The absence of the England midfielder increases the chance of Jurgen Klopp handing a first start for new signing Thiago Alcantara, who was Henderson's replacement at Stamford Bridge.

"We will see, we will see. We have a few days to train, some boys have to recover from last night (the 7-2 League Cup win over Lincoln) so we will see how we set up against Arsenal," said Reds boss Klopp when asked about the Spain international's ability to start after only 45 minutes game-time.

"I have an idea, but why should I make the decision today when we have time until Monday? But he is in contention, for sure. Yeah, let's see."

Klopp received some good news with Joe Gomez returning to training, giving the manager the option of restoring his first-choice centre-back partnership, having played Fabinho there last weekend.

He added: "Joe should be back in training. Billy the Kid (17-year-old Billy Koumetio) is back in training. Joel (Matip) is not. Hendo is not yet, this game is for sure too early."

While much of the focus has been on Liverpool's new arrivals, with Diogo Jota making a second-half debut against Lincoln and set for inclusion in Monday's squad, attention is now turning to fringe players who may be offloaded.

Klopp's Arsenal counterpart Mikel Arteta believes club-record signing Nicolas Pepe will be at the club for years to come after seeing "big developments" in his game. Pepe, 25, joined last summer from Lille for a fee of £72m but - despite showing flashes of his ability - the forward largely struggled to settle in his first season at the Emirates Stadium.

He has not started either Premier League game so far this season as new recruit Willian has been preferred.

Despite dropping back down to the role of substitute, Arteta insists he remains convinced that Pepe will remain a key member of the Arsenal set-up in the coming years.

"I think he has come a long way, Nico," he said. "Obviously we know what the club paid for him when he joined and that was an extra pressure.

"He is a really good character to have around and I'm really positive we are going to have him for many years. But he is a player who had to adapt, it is a different style and he has a really good attitude and we can see big developments in a lot of places in his game.

"He is very settled, he is liked by the boys, he is a really good character to have around and I'm really positive we are going to have him for many years and that he can perform at a really high level consistently."
