Liverpool have been dealt another defensive injury blow after Trent Alexander-Arnold was ruled out for a month with a knee injury.

The England international right-back sustained a problem in the warm-up against Albion but played the full 90 minutes in Saturday's 1-0 win at the Amex.

He is understood to have tweaked ligaments.

With former Albion loan target Joe Gomez still working his way back to fitness after a broken foot and Nathaniel Clyne loaned to Bournemouth earlier this month, it leaves manager Jurgen Klopp short of options.

James Milner appears the likely candidate to start at home to Crystal Palace on Saturday, although fellow midfielder Fabinho - who played centre-back at the weekend because Joel Matip, Joe Gomez and Dejan Lovren are not fully fit - could potentially fill in.

Matip was an unusued substitute against Albion on his return from a fractured collarbone.
