Theo Walcott believes Tuesday’s Champions League Semi-Final second leg with Manchester United is the biggest game in the careers of Arsenal’s young squad.

Arsène Wenger’s side were somewhat fortunate to leave Old Trafford last week with only a 1-0 deficit. The aim in the return rubber is to turnaround the performance as well as the result. For Walcott it is the most important match he and most of his team-mates have ever played.

“Man United is the biggest game of our careers,” said the 20-year-old. “It's massive and I think we can do it as well. We have a lot of experience in the Champions League and hopefully, we can create some chances.

“We have to believe that we can get the result. Hopefully the performance against Portsmouth will spur us on as well. A lot of players didn’t travel there on Saturday and that will help us.

“Everyone is buzzing, we cannot wait and we're on our own pitch, in front of our own fans. That will be crucial and hopefully, we can do it for them because they have been excellent for us this season”
