The Reds haven’t won in their last three friendly fixtures, losing 3-2 to Dortmund and 2-1 to Sevilla before a 2-2 draw with Sporting CP on Thursday.

The two sides met each other in the Champions League group stage and Liverpool failed to overcome the Partonopei.
But after their Champions League success in June, it could be a very different story at Murrayfield on Sunday evening.
