The England international's deflected cross moved Arsene Wenger's side closer to securing third place in the Premier League and was pleased with claiming a point at Old Trafford.
Theo Walcott feels he needs more playing time if he is to get back to his best after his equalizer sealed a point for Arsenal against Manchester United.
The England winger's cross deflected off Tyler Blackett to cancel out Ander Herrera's opener in a result which left the Gunnners on the verge of securing a place in the Champions League group stage.
Walcott, who missed nine months with a ruptured cruciate ligament in 2014, feels he requires more than cameo appearances off the bench if he is to continue having an impact.
