The Swiss club managed to overcome City's neighbours Manchester United in a 1-0 victory in the group stage.
Now, in the last-16 stage, they go head to head with a Pep Guardiola team that have lost just twice in all competitions this season.
"They are many factors, but I think the team has no weaknesses, they show that every three days in all competitions," The Mirror quotes Wicky as saying.
"They are a very flexible team and are able to react very well to the opposition. We don't have to talk about the quality of the opponents or the coach.
"Pep Guardiola's way of football, his philosophy, he developed [at Barcelona], then Bayern Munich and you can see that now at Manchester City."
City head into the fixture on the back of a 5-1 thumping over Leicester City in the Premier League.
