Liverpool know they face a huge task in turning around their Champions League deficit on Tuesday night and who they have to stop if they are to have any hope of reaching the final next month.
The Reds trail 3-0 to Barcelona after a first leg that saw Lionel Messi stamp his class with a brace - despite a bright team display from the Premier League outfit.
Tuesday's return leg at Anfield will just be Messi's second-ever competitive match at Liverpool's iconic ground.
The fixture will be the 31-year-old's 16th against a Premier League club on English soil - with the Argentine boasting a decent record of seven wins and three draws from 15 matches.
Messi has only visited Anfield once before - a 1-0 win in the Champions League last-16 second leg in March 2007. However, it was Liverpool who went through 2-2 on away goals.
That match came in a run of his first eight games in England when he failed to score. Jurgen Klopp and Co will hope Messi fires a similar blank on Tuesday night.
