Kristoffer Zachariassen has been giving away plenty of fouls this season, averaging almost two per 90 minutes.

In midfield, the Norwegian could come up against Yunus Musah, who's been fouled in each of his last four starts, including twice in each of his last two.

Three opponents have already been booked for fouling the Milan midfielder this season, including one against Benfica at home in the Europa League.

Zachariassen has already picked up a yellow in the Europa League himself, while Ferencváros are averaging three yellows and more than 14 fouls per match.

Including the Europa League qualifiers, Zachariassen has given away at least one foul in 10 of his 11 games and will have plenty of defensive work to do against a Milan side that've been drawing more than 14 fouls per game in the competition.

Leon Avdullahu has been giving away more fouls in the Europa League, with seven in three games, including three against Beşiktaş and another three against Lyon.

Hoffenheim have also been one of the most poorly disciplined teams in the competition, averaging 20 fouls and four yellows per match.

Avdullahu will be up against a Crystal Palace side with players like Adam Wharton and Daichi Kamada in midfield.

Both have been fouled 14 times this season, while Yeremy Pino leads the team with 15 and has scored in every Europa League game.

The referee is another concern.

Horațiu Feșnic is averaging almost five cards per game this season and giving 26 fouls per match.

That's not good news for Avdullahu, who's picked up three yellows this season, including two in his last three games.
