Arsenal wing ace Theo Walcott is determined to make a big impact at Liverpool on Sunday.

Walcott says he's fully fit and ready to take on Liverpool.

"Hopefully if I get a start I will play my heart out," Walcott told arsenal.com.

"I was a Liverpool fan when I was younger and I have always played very well there. It always brings back happy memories, so if I am called on from the bench hopefully I'll do a job.

"There are a few teams involved in the title race and we are definitely one of them. We are strong candidates.

"With Chelsea losing we and other clubs can catch them up now and Liverpool are always in the top four and these are the games we need to win, especially away from home. So we are going to go right at it. All the first-team players have had a good rest, so hopefully they should be right at it."
