Olivier Giroud struck in the 89th minute to earn Arsenal a 1-1 draw against Manchester United at Old Trafford.
United looked destined for a home win after Juan Mata had given them the lead with a 68th-minute strike, the Spaniard converting Ander Herrera's cross.
But with the clock ticking down two substitutes made the difference for Arsenal, as Alex Oxlade-Chamberlain's right-wing cross was powered past David De Gea by Giroud.
Petr Cech three times denied United in the first half, but could not stop Mata's low shot midway through the second.
Marcos Rojo might have made it 2-0 but headed wide and it came to haunt United as Arsenal’s first goal against a Mourinho side for nine years in the Premier League ensured they escaped with a point.
