Arsene Wenger claims there is more to come from "electric" Theo Walcott after the England forward's hat-trick brought Barclays Premier League newcomers Blackpool back down to earth with a crushing 6-0 defeat at Arsenal.
The 21-year-old was a controversial omission from Fabio Capello's ill-fated World Cup squad, only to be welcomed back into the England fold following the dismal display in South Africa. Walcott produced a stunning performance as he tore the Seasiders apart from kick-off.
"Theo is more electric than he has been," said Wenger.
"He mixed well the final ball and the finishing, which is a sign a player is more mature.
"Let's not forget what he does is always at a very high pace, so it is not easy to make the right decision, but in this game, he did."
Wenger added: "Theo is 21, so now he is at an age where players usually start, you cannot say he is at the peak of his game.
"There is a lot to come from him. First, he has to keep his attitude right and also to be injury free, because that decides careers as well."
Wenger suggested Walcott will use a summer of disappointment to become stronger.
"Theo is a guy who keeps his feet on the ground, and takes life in a positive way - he sees always the glass is half full, and not half empty," said the Arsenal manager.
"He took the World Cup as another challenge, and that is what is amazing about Theo."
