Substitute Nicolas Pepe rescued Arsenal with two sublime free-kicks in the last 10 minutes of their Europa League group game against Vitoria Guimaraes at Emirates Stadium.
Arsenal were losing 2-1 when Pepe came on in the 75th minute and he scored five minutes later with a curling effort from 25 yards.
He repeated the feat in stoppage time as Arsenal avoided their second straight defeat and retained their place at the top of Group F.
