Trent Alexander-Arnold is out for four weeks against the Reds’ ambitions

Liverpool’s quadruple bid has suffered a major setback after it was revealed Trent Alexander-Arnold suffered a hamstring injury in the win over Arsenal.

Anager Jurgen Klopp confirmed the right-back would be out for “weeks” – starting with tomorrow’s FA Cup quarter-final against Nottingham Forest and forcing his withdrawal from the England squad.

Liverpool are hoping the 23-year-old is back in time to face Manchester City for a crucial meeting in the title race on April 10, but Klopp will have to turn to one of James Milner, Joe Gomez or youngster Conor Bradley tomorrow represent.

“It’s difficult. We’ll see how long it takes,” said Klopp. “Replacing Trent is difficult but possible. We have James Milner and Joe Gomez and theoretically we can change the system too. Trent is so influential, but Milner has done incredibly well in the past.Maybe we have a very recent solution [Bradley] even.”

Klopp again requested five substitutes in the Premier League, suggesting Alexander-Arnold’s setback is directly related to the demands on modern players.

“The five submarines are essential,” he said. “I think Scotland are planning six friendlies over the summer, not all with the aim of ‘if we go to the World Cup we’ll be better prepared’. For money reasons. England has four games. In the summer – where there is no tournament for the first time in ages – what do we do? Insert new games.

“Just accepting that top players get injured more often than others doesn’t make sense. If I heard that with six and four games in the summer break and then a normal season, plus a World Cup in the middle, how does that work? You think these guys can do it. You have to have every second to recover, it’s really tough.”

Klopp also has an injury concern for Mohamed Salah, who was only fit enough for a bench spot in Wednesday’s win at Arsenal. “Mo felt his foot a bit after the game so we’ll have to see.”
