|7/1||Arsenal are 7/1 with William Hill to beat Aston Villa 2-0|
A goal in each half from Santi Cazorla and Tomas Rosicky secured Arsenal's passage to the fourth round of the competition, where they will face Coventry City on home soil.
"He'll be an Arsenal legend now," Wilshere told reporters. "They love Theo already and this is only going to help him.
"[The Tottenham supporters] were giving it to him and he's given a little bit back. I think people have got to look at it as banter."
Wilshere, who was recently banned for two matches after he made an offensive gesture aimed at Manchester City fans, added: "He's a bit smarter than me, I suppose."
