Jurgen Klopp’s Liverpool said star right back Trent Alexander Arnold will be out of the team for “weeks” with a hamstring injury.

Liverpool have been dealt the blow as they prepare for a tough FA Cup quarter-final away at Nottingham Forest.

However, after an impressive victory against Arsenal, the Reds have been dealt two serious injury blows.

Klopp said: “Trent is out with hamstring.

“It will mean he cannot be part of England as well. Not good news, we will see how long that takes.

“Mo (Salah) hurt his foot again after the game so we’ll have to see what we do with that. We have to wait.”

Liverpool will undoubtedly miss the Premier League’s top assist maker this season when they travel to the City Ground to take on dark horses Nottingham Forrest.

However, Klopp feels they will find ways to cope without their star man.

The German said: “We will see how long it’ll take to replace Trent.

“To replace Trent is difficult, but possible.

“Theoretically we can change system as well, so we have a couple of options.

“If you have a look at the past Milly (James Milner) did incredible to step in. How Milly will be for Sunday? I don’t know at the moment.

“If not. Maybe we have a young solution? Which is fine as well. Or Joey (Joe Gomez), so we’ll have a look.”

Potentially being without a number of key players for their away trip, Klopp has stressed the importance of a strong side against a team who have already knocked out three Premier League sides this season.

Klopp said: “I want to have a team at Nottingham who is fresh enough, physically and mentally for the game, and really going for it.

“We are Premier League team number four for Nottingham, they didn’t have an easy way here but made it.

“Our former LFC coach (Steve Cooper) is obviously doing a proper job there!

“If we rotate, it’s just to have the best team possible.”
