Celtic face Russian giants Zenit St Petersburg in the UEFA Europa League round of 32.
Celtic will host Roberto Mancini's Zenit Saint Petersburg at Celtic Park on Thursday night in the first leg of their Europa League last 32 tie.
The Hoops dropped into the Europa League after finishing third in their Champions League group, while their opponents were unbeaten during the group stage.
Zenit have been tipped to go far in the competition so it is certainly going to be a difficult tie for Brendan Rodgers' team. Here are three players who could cause them a few problems:
Aleksandr Kokorin is Zenit's top scorer with 18 goals so far (eight coming in Europe). The Russian international is having the best season of his career.
The 26-year-old is the man Russia will be pinning their hopes on during the World Cup in the summer and he has 12 goals for his country. As well as good finishing ability, Kokorin holds the ball up well and is good at bringing others into play.
Zenit captain Domenico Criscito is one of the clubs most important players. The Italian mainly plays at full-back but he can also play as a wing-back or as centre-half. He is effective defensively and going forward as he can create and score goals.
He has played 211 times for Zenit, scoring 18 goals while he also has 22 caps for Italy. His defensive team-mate Branislav Ivanovic is similar in terms of his ability both defensively and offensively so deserves a mention.
Argentinian forward Emiliano Rigoni has been one of Zenit's best performers in Europe this season. He has already netted six times in the Europa League, including a hat-trick against in a 3-1 triumph over Rosenborg.
The attacking midfielder is also one of Zenit's more creative and technically gifted players.
