Swansea scored twice in less than three minutes to rally to a 2-1 victory over Arsenal in the Premier League on Sunday, with substitute Bafetimbi Gomis grabbing the winner with one of his first touches.

A listless game played in driving rain in south Wales was illuminated by Alexis Sanchez’s close-range finish in the 63rd minute, the Chile forward scoring for the fourth straight league game.

Gylfi Sigurdsson curled home a stunning free kick to equalize for Swansea in the 75th and Gomis completed the hosts’ recovery by rising high to head home a pin-point cross from Jefferson Montero, barely 90 seconds after his introduction.

The defeat ends a miserable week for Arsenal after it surrendered a 3-0 lead to draw 3-3 against Anderlecht in the Champions League on Tuesday.
