Zenit boss Sergei Semak has heaped praise on Thomas Tuchel’s “well-oiled” Chelsea team.
Chelsea travel to face Zenit in St Petersburg on Wednesday, where the Blues can seal top spot in Champions League Group H.
“You’re talking about individual players but I would like to point out the importance of the system in general, they are like a German machine, well-oiled,” said Semak.
“Every person on the pitch knows what to do and how to do it.
“So I would like to refrain from talking about individual qualities, and concentrate more on Chelsea as a team.”
