Arsenal forward Theo Walcott believes he has given manager Arsene Wenger a selection headache ahead of the FA Cup final against Aston Villa.

The 26-year old scored a first-half hat-trick in the 4-1 win against West Bromwich Ablion on Sunday and made a serious claim for a starting spot in the cup final at Wembley on Saturday.

"Today it's gone for me. I'm sure the manager's got an absolute headache to pick his best team, but it just shows our squad is fantastic as well and it's a squad that should be challenging for the Premier League," Walcott told Sky Sports on Sunday.

And when asked whether he had done enough to earn a spot in the cup final starting line-up, he said: "We'll have to ask him[Wenger] that. Like I said, our squad is remarkable when everyone is fit. It's always difficult to have a whole team fit throughout the season, but to be fair, we've had that.

"It's something the manager will be judging come matchday and I'll be giving him a headache I'm sure. All I want to do is play well for this club and see where it takes me."
