Midfielders
Central midfielder: Marco Verratti | PSG
PSG have one of the best attacks in Europe at the moment but they are not so solid in midfield. Marco Verratti is the only standout player in the middle of the park for Pochettino. He is a guaranteed starter for the French side and is expected to have a great duel against Casemiro in midfield.
The Italian midfielder is equally adept in both his defensive duties and while going forward. While he does not score or provide assists very often, he is crucial to PSG's attacking buildup.
He recovered from an injury layoff earlier this season and having returned to full fitness, adds some much-needed flair to PSG's midfield. While he is without an assist in the Champions League, he has picked up one in the league so far.
He will be the one to watch out for in this game.
Central midfielder: Toni Kroos | Real Madrid
Toni Kroos is one of the best midfielders of his generation. Regardless of how his side perform, the German midfielder usually delivers a top-notch performance. He is a supreme pass master and has maintained a 95.8% pass success rate in the Champions League.
He has also scored two goals in the competition, including a left-footed shot from outside the box against Inter Milan. He has also completed 95% of his passes in La Liga this season, and will look to be the key creative force against PSG in this game.
His ability to dictate play makes him stand out in midfield and he is a starter in any given starting XI.
Defensive midfielder: Casemiro | Real Madrid
Casemiro is one of the best defensive midfielders of his generation and provides an effective shield to his defenders. The Brazilian midfielder has posted even better defensive stats than his defenders this season.
He makes more successful tackles per game in La Liga (3.1) than any of his teammates and also leads the tackles' chart in the Champions League. (2.3 per 90).
Casemiro has helped Real Madrid to four Champions League trophies so far and remains a key player in the search for their 14th continental title. He has also completed 91.4% of his passes in the continental competition this season.
