MANCHESTER, England -- Paul Pogba walked off the pitch alone after once again playing a central role in Manchester United's downfall. The France international midfielder's needless foul on Hector Bellerin on 68 minutes resulted in the penalty from which Pierre-Emerick Aubameyang scored to seal Arsenal's first league victory at Old Trafford since 2006.
Pogba, who has always lacked defensive qualities, conceded another penalty in the 6-1 home defeat against Tottenham last month when a similarly thoughtless challenge on Ben Davies led to a penalty for the opposition.
