English clubs are back in Champions League action again this week as the final round of group stage matches takes place.
Liverpool, Manchester City and Chelsea have already guaranteed their places in the knockout stages but Manchester United still have work to do in Germany against RB Leipzig if they are to join their Premier League rivals in the round of 32.
Here, the PA news agency takes a closer look at the opposition clubs.
FK Krasnodar: Formerly in charge of the club’s under-19 side, Murad Musayev was appointed as head coach in June.
Marseille: Andre Villas-Boas will be familiar to fans of English football, having managed in the Premier League at Chelsea and Tottenham. He has been in charge at the Stade Velodrome since May 2019. Villas-Boas won the Europa League with Porto in 2011.
FC Midtjylland: Former Denmark international defender Brian Priske served as assistant at Midtjylland and Copenhagen from 2011 to 2019. When Kenneth Andersen resigned as boss of the Danish club in August 2019, Priske succeeded him.
RB Leipzig: The club, formed in 2009, hit a new high in Europe last season by reaching the Champions League semi-finals. They beat Tottenham home and away in the round of 16 and saw off Atletico Madrid before losing 3-0 to Paris St Germain.
