Arsenal boss Arsene Wenger is looking for more consistency from Theo Walcott.
"When a guy comes on and makes a difference, he doesn't stay a long time as a substitute," said Wenger.
"That is what is good in the attitude of our players, they come on with a real desire to affect the game.
"The next step is for him to be consistent, not injured, score goals, make assists, affect games and play well away from home."
