Arsenal warmed up for their FA Cup final clash with a straightforward home win over West Brom.
Winger Theo Walcott, who has endured a frustrating season struggling with both fitness and form, fired home an opening Arsenal goal with a superb angled effort after just three minutes.
The 25 year old England man then doubled the lead soon after after the Baggies failed to clear their lines.
The game was over as a contest on 17 minutes as midfielder Jack Wilshere, who has also not enjoyed the best of seasons, smashed in a wonder-strike to make it 3-0 to the home side.
Theo Walcott completed his hat-trick on 37 minutes as he poked home a Santi Cazorla effort that may or may not have been trickling over the line.
Gareth McAuley pulled a goal back after keeper David Ospina got lost in the crowd from a corner.
The win will hold Arsenal in goal stead ahead of their big cup final clash next weekend and the display from Walcott may just earn him a spot in the Gunners starting eleven.
