Arsenal conceded a 1-1 draw at home to Brighton and was virtually out of the Champions League places in fifth place on a journey to the final of the English Premier League.
The poor result leaves the Gunners three points from last place for Tottenham's 'Champions', who are fourth with three points and the best difference between goals scored and conceded.
For Arsenal to reach fourth place they would have to win out Burnley, Tottenham lose at home to Everton, and be able to beat the spurs' eight goals (65-37 against 70-50 ).
Today, at Emirates Stadium, the game was set on penalties, with Aubameyang scoring for Arsenal in the ninth minute and Glenn Murray equaling for the 11-meter Brighton in the 67th.
The fourth consecutive championship run in a three-game losing streak and a draw may still not be catastrophic for the London team, which, via the Europa League, and in the event of a final victory, may still be in the next edition of 'Champions' .
Chelsea, no matter what they do in the Europa League, won today in the 37th round of the English League, Watford 3-0, ensuring that they will finish in third or fourth place .
At Stamford Bridge, the only goals came in the second half, Loftus-Cheek at 48 minutes, David Luiz at 51, and Higuain at 75.
Without any chance of being in the European elite were Manchester United, with the team to add the fourth game without a win, with two defeats and two draws, the last today against the relegated Huddersfield.
Scott McTominay scored for the red devils in the eighth minute but Mbenza equalized for Huddersgield in the 60th, setting the score and leaving United in sixth place, one point behind Arsenal, but four behind an unassailable fourth.
