Paul Robinson claims Liverpool have suffered a “huge blow” after it was reported Trent Alexander-Arnold faces up to a month out with a calf injury.

Speaking exclusively to Football Insider correspondent Dylan Childs, the former Spurs and Leeds United goalkeeper fears that the 22-year-old is irreplaceable and the Reds must sign a new defender as soon as the January window opens.

The England international was replaced by James Milner just after the hour mark of the 1-1 draw with Manchester City on Sunday.

The Times’ Paul Joyce revealed yesterday that Alexander-Arnold will be sidelined for up to four weeks.

He is therefore likely to miss Premier League fixtures against Leicester City, Brighton and Wolves as well as Champions League games against Atalanta and Ajax.

When asked by Football Insider to what extent Jurgen Klopp’s side would miss the creative full-back, Robinson said: “It is another big, big blow for Liverpool.

“It really is when they have already got Virgil van Dijk out for such a length of time.

“It is an area that Jurgen is going to have to address in the window, especially at centre-half. It cannot drag out. It has to be done on the 1 January.

“It is a huge blow having Trent out.

“Yes, they have players who can cover that position but he brings so much to the team going forward with his assists and free-kicks – he brings so much to the team.

“Players can fill that void but there is only one Trent. Another big blow for Jurgen.”
