Arsene Wenger played down Alexis Sanchez's frustration at being substituted in Arsenal's 4-0 Premier League victory at Swansea.
Sanchez had scored Arsenal's fourth goal - his 16th of the season - before being withdrawn 11 minutes from time with the Gunners moving in to the top three on goal difference.
The Chilean forward - who showed his frustration at the final whistle of Arsenal's last league game, a 3-3 draw at Bournemouth - responded to his substitution by kicking his gloves on the touchline.
