Full-Backs
The competition for the right-back spot is really tight. Madrid's Dani Carvajal has been in the business for quite a while and is one of the best right backs in the world. The Spaniard plays an important role in his team's attack and is also solid at the back.
However, Trent Alexander-Arnold seems to have a slight edge over his counterpart when their performances in the Champions League are compared. The 19-year-old has made nine tackles, 28 clearances and recovered the ball 61 times - all of them better than Carvajal's numbers.
The youngster also scored the first goal for Liverpool in the campaign against Hoffenheim.
Liverpool's Andy Robertson has been solid for his team and is one of their best players this season, but the Scotsman is no match for Marcelo.
The Brazilian left-back has scored three goals and assisted two in Real Madrid's Champions League campaign, showing his influence in the Spanish team's attack. Facing the 30-year-old will be Alexander-Arnold's biggest challenge on Saturday.
Robertson's runs and crosses also have the potential to cause some trouble to the Real Madrid defence.
