Trent Alexander-Arnold will miss Liverpool's FA Cup tie against Nottingham Forest and is unavailable for England duty due to a hamstring injury, Jurgen Klopp has confirmed.

The full-back, who was named in Gareth Southgate's latest England squad on Thursday, will be forced to miss the Three Lions' March international friendlies against Switzerland the Ivory Coast.

The Reds travel to the City Ground on Sunday in pursuit of a semi-final place, a few weeks on from claiming the EFL Cup against Chelsea at Wembley.

Victory would take them one step closer to a potential quadruple, with Klopp's side still in contention for both the Premier League and Champions League too.

But they will have to do so this weekend without Alexander-Arnold, while Mohamed Salah could be a doubt for the visitors too.

"Trent is out with a hamstring, so will be out for England too," Klopp told his pre-match news conference. "[It's] not good news, [but] we will see how long it takes. Mo felt his foot a little bit after the game too."

Asked on how his side would cope without Alexander-Arnold, Klopp added: "We will see. To replace him is difficult but possible.

"We have [James] Milner, [Joe] Gomez, these kind of things. Trent is so influential but Milner has done incredibly well in the past. We'll see how [he] is for Sunday."

Liverpool are set to play their first FA Cup quarter-final under Klopp, with the trophy one of the few gaps on his resume since he arrived on Merseyside.

If he is able to guide them past Forest - themselves in the last eight for the first time since the 1995-96 campaign - then the Reds will move a step closer to further silverware this season.
