These two teams struggled in the Champions League group stages last season and they will be looking to have a better outing this time around.
Monaco were semifinalists in the 2016/2017 season, but finished bottom of their group last season, while Atletico had to settle for the 3rd spot in their group as AS Roma and Chelsea claimed the top two spots.
AS Monaco struggled so much in the Champions League last season that they failed a single group game.
They also failed to challenge for the Ligue 1 title last season even though they finished the season in 2nd position.
This season, the French side has sold over £300 million worth of talents, so they will be playing this competition with a new set of players that may not have blended well with each other.
Atletico went all the way to win the Europa League last season after they failed to make it through the group stages.
They have reached two finals of this competition in the last four years, but their early season form does not quite stand out as La Liga or Champions League favourites.
Atletico beat Real Madrid in the Super Cup and from there they have won just one league game so far and were well beaten when they visited Celta Vigo on matchday 3.
AS Monaco have also not started this season well as they have won just one of their opening five league games, so this game could turn out to be a boring encounter between two underachievers.
This is the first time these teams are meeting in recent years.
Bookmakers make Atletico Madrid odds-on favourites to come out on top despite their poor recent form.
