No less than eight of the managers competing in this season's Champions League group stage previously faced Chelsea in their playing careers, including the boss of our next opponents Malmo, but who are they?
Several of the other teams taking part in the group stage of the 2021/22 Champions League are managed by people who we have faced during their playing careers, both in Europe and the Premier League.
That number includes two of the three sides drawn against us in Group H, but can you identify all eight of them in our quiz below before we meet one of them again in our next match against Malmo in Sweden? Good luck!
