Arsenal were held to a 2-2 draw at Sporting in a Europa League round-of-16 tie that saw the lead change hands.
The Gunners made the trip to the Estadio Jose Alvalade aiming to return to North London with a healthy advantage ahead of next week's second-leg at the Emirates. However, it was actually the hosts who started the brighter of the two sides.
Sporting couldn't make their early pressure tell and as a result were duly punished, as William Saliba headed Arsenal in front just over 20 minutes in from a delightful Fabio Vieira corner.
