Arsenal will find out their Europa League round of 16 opponents tomorrow.
The north Londoners topped their group which consisted of PSV, Bodo/Glimt and FC Zurich, meaning they didn't have to partake in the recent round of 32 which took place over the last week. This, combined with the fact that the Gunners are no longer in the FA Cup or Carabao Cup, has allowed them to have most midweeks free.
The extra rest has helped Mikel Arteta's men mount a serious Premier League title challenge, currently sitting two points clear of second-placed Manchester City, who have also played an extra league match this term. However, Arsenal are in action in each of the next three midweeks, playing Everton in the league on Wednesday night before their European knockouts get underway on the two following Thursdays.
