The Europa League group stage begins on Thursday night as Arsenal line up against FC Koln of the Bundesliga in the first round.
Whilst many fans may have to get used to watching the Gunners on a Thursday night, the competition does allow Arsene Wenger to field some squad players who were unable to play in the Champions League or the Premier League.
Players that are finding it difficult to get a run in the league may be given an opportunity to showcase themselves and be in contention for a starting position in the first team line up.
With a game at Stamford bridge following the Europa League tie, some players will surely work hard to be selected in the squad to face the London rivals. Others will hope that the Europa League can be an introduction to a breakthrough season.
These are the players to keep an eye out for during the group stages.
