Arsenal manager Arsene Wenger has defended Theo Walcott for making a 'non-offensive' gesture towards Tottenham supporters.
It was after the England forward was pelted with missiles as he was carried off towards the end of the 2-0 FA Cup third-round tie at the Emirates Stadium.
The Gunners booked their place in the fourth round draw after Santi Cazorla drilled in a fine opening goal on 31 minutes, before Tomas Rosicky doubled the lead on the hour with a well-taken finish after robbing Danny Rose on the halfway line and sprinting clear.
There was, however, a controversial end to what had been a fiercely contested north London derby when Walcott was taken off on a stretcher with a knee injury.
