Arsenal snatched a difficult victory from Manchester United with a clean goal at the top of the seventh round of the English Premier League, which also saw Newcastle beat Everton 2-1, and Southampton over Aston Villa 4-3.
Gabonese player Pierre Emerick Aubameyang scored the winning goal in the 69th minute, with a penalty kick.
Arsenal raised its score to 12 points in eighth place, and Manchester United stopped at 7 points in the 15th place.
This victory is the fourth for Arsenal in the league this season compared to a loss in 3 games, while this loss became the third for Manchester United, who has a game in delay, compared to winning two games and a tie.
Aubameyang became the second Arsenal player to score in "Almanio" at their home, "Old Trafford", in two consecutive matches.
The first player to reach this record was Togolese Emmanuel Adebayor, who scored at Old Trafford in September 2006 and April 2008.
It is noteworthy that Arsenal managed to break its knot in the "theater of dreams", after it was unable to win in the "Red Devils" stronghold in the Premiership, in 13 consecutive matches (8 wins and 5 draws) since September 2006.
