Manchester United or AS Roma await the winners of tonight in the Europa League final with the guaranteed Champions League place.
Chelsea beat Real Madrid last night to get in the Champions League final against Manchester City.
That means Chelsea can finish fifth and still qualify for the Champions League if they beat City in the final.
If Chelsea win the Champions League final and Arsenal win the Europa League final the Premier League fourth place would be stripped of a Champions League as only five teams from one country can qualify in any one season.
