Theo Walcott says the key to Sunday’s thrilling comeback against Aston Villa was the players’ complete belief in each other.

Trailing 2-0 at half time at Emirates Stadium, Arsenal appeared to be on the brink of an early FA Cup exit before Robin van Persie struck twice and Walcott once in an incredible seven-minute spell.

Walcott says Arsène Wenger remained calm at the break and urged his side to show their battling qualities.

“He was very clear with his messages because obviously we really wanted to win the game. It was disappointing to go into half time 2-0 down when we probably didn't deserve to be, but credit to Aston Villa,” said Walcott.

“He just believed in us; we all had to believe in each other in the second half. It just shows the number of characters we have got in that dressing room. We worked hard - there are a few people who can't even walk in there!”

Walcott also paid tribute to Van Persie, after the striker claimed his 24th and 25th goals in all competitions this season.

“He's the captain and he just showed again how much he believes in this team and how much he wants to win this competition. He knows that we have got it in us, we have all got it in us,” he said.

“Hopefully something came out of us today that we can turn into Premier League form, which hasn't been great lately. Hopefully our luck has changed now.”
