Liverpool defender Andy Robertson insists his injury is ‘nothing too major’ but ankle ligament damage will rule him out of the Premier League opener at Norwich.

The Scotland international had to be helped off the pitch in Sunday’s friendly with Athletic Bilbao and further assessment has revealed a problem which will prevent his involvement this weekend.

The Scot was left in agony on the turf clutching his left ankle after deflecting Alex Berenguer’s cross behind for a corner late in the first half before hobbling off.

‘Thanks to everyone for the kind messages and support,’ Robertson wrote on Twitter ahead of the Reds final pre-season friendly against Osasuna at Anfield.

‘Scan suggests nothing too major but there’s some ligament damage which will need to mend,

‘I will be grafting every day so I can help the team again sooner rather than later.’

Team mate Trent Alexander-Arnold who recently returned from injury and played in the friendly against Bilbao offered encouragement to the Scotland left-back.

‘I think you know it’s going to be quite bad if Robbo has to come off.’ He said after the 1-1 draw against the LaLiga side.

‘It’s not something that he normally does so it’s disappointing to see, but I’m sure he will bounce back as soon as he can.’

His injury makes it increasingly likely that Kostas Tsimikas, who managed just six Premier League minutes in his maiden campaign for the Reds last season, will make his first league start at Carrow Road.
