Liverpool are now sweating on the fitness of Andy Robertson after the left-back was left in considerable pain after appearing to badly roll his right ankle.
The Scotland captain, who was able to limp off the pitch with assistance, sustained the injury during Sunday’s pre-season friendly against Athletic Bilbao.
Robertson chased down Alex Berenguer and attempted to block his cross before half-time, only to go over on his right ankle.
Left writhing in pain in front of the Kop, teammate Naby Keita instantly rushed to the stricken Scot before the medical team had a chance to asses.
The 40,000 fans inside Anfield gave the defender a raucous round of applause as he walked off with the assistance of the physios and with a look of discomfort etched on his face.
Kostas Tsimikas was being held back for Monday’s friendly against Osasuna, so teenager Owen Beck was handed his chance by Jurgen Klopp.
Robertson appeared in every Premier League game last season, but now faces an anxious wait before Saturday’s season opener against Norwich City.
Diogo Jota opened the scoring for the hosts, before Berenguer levelled the scores in the second half against the 2019/20 Premier League champions.
