The Opta SuperComputer has predicted the top four teams that could win the UEFA Champions League this season.
The competition enters Match Day 2 this midweek, with holders Paris Saint-Germain sitting at the top.
Bayern Munich, Barcelona and Manchester United complete the top four.
But Opta has said Arsenal is most likely to win the trophy and has given the Premier League champions a 21% chance.
Manchester City have 18% chance, while Bayern are third with 17%.
Barcelona, who have stumbled at the latter stages of the competition in recent seasons, have a 9% probability.
