We brushed aside Southampton on Saturday evening as we continude our Emirates FA Cup adventure.
Having overcome Preston in the third round, the Saints were the next test - and the deadlock was broken after just 15 minutes, with Danny Welbeck scoring on his first start since returning from injury.
Welbeck added a second just seven minutes later, with Theo Walcott finding the net in the 36th minute to send us in with a three-goal lead at the break.
Two second half strikes from Walcott wrapped up the scoring, with Arsene Wenger's side progression to the last 16 of the competition.
