Since joining Liverpool in a £10m deal from Hull, Andy Robertson has established himself as one of European football's most dangerous full-backs. The 25-year-old has racked up 20 assists in his time at the club, with 11 of them coming in the Premier League alone last season.

Whilst he has been a consistent performer for Jurgen Klopp's side, the jury is out when it comes to his displays at international level. The left-back has struggled to replicate his form with Scotland, and has been involved in some of the side's heavy losses in recent months - not least their 4-0 drubbing at the hands of Russia on Thursday night.

Although Steve Clarke's men were quite poor as a whole, Robertson in particular had a performance to forget. The Reds defender didn't look his usual self, and the graphic below really paints a sorry picture of the 25-year-old's miserable night.

In his time at Anfield, Robertson has become renowned for the chaos he can cause with his marauding runs down the left-flank. The endless energy and pin-point crossing has become a common theme under Klopp, but on Thursday night, those abilities seemed to desert him.

As per SofaScore, he failed to complete the only cross he attempted, whilst his pass accuracy came in at a measly 78%. In contrast, the Scotland international has averaged an impressive 85.3% in the Premier League. Unfortunately for him, his usually tenacious defensive skills were also nowhere to be seen.

In the top-flight, the former Hull City man has won 3.8 duels per game, but against Russia, he could only muster up one. His solitary interception and zero number of tackles all perfectly encapsulated the kind of timid display he put on. It was therefore no surprise to see the Scotland faithful completely savage his virtually anonymous showing, with some even questioning his status as captain.

The Jekyll and Hyde mystery surrounding Robertson's contrasting performances for club and country, continues to remain unsolved.
