Chelsea centre-back Fikayo Tomori will come up against Ajax striker Dusan Tadic on Wednesday night.
The former Southampton striker was recently included in the list of nominees for the Ballon d’Or after helping Ajax reach the Champions League semifinal last season.
Asked about the threat of Tadic, Tomori said: “Last year in the Champions League, Ajax did so well and he was a very big part of that.
“We know the kind of movements he likes to make. He’s not the typical number nine running in behind, he likes to play with the ball and link up with the whole team.
“Sometimes as a defender you have to make a decision on the spot and go in to mark, or sometimes you have enough time to communicate to the midfielders in front of you.
“I’m sure the game will throw up those different situations and we’ll have to deal with it and that’s just part of the game.”
