Davies has enjoyed a good record against the Gunners this season.
But he says: "You meet different players every week and just have to try to beat them. Theo Walcott is one of the best players I have faced. He is incredibly fast and difficult to handle.
"He is a great test for everyone, but I think I have shown that I can play against him. I have already met him twice this season. There is no reason not to enjoy it. He is a top player, otherwise he would not have a new contract with Arsenal."
