Arsenal manager Arsene Wenger has revealed that he will take a final decision on Saturday over who will start in attack against Chelsea.
Striker Theo Walcott scored four goals in three games for the Gunners but the 65-year-old could opt for the Frenchman against the strength and tenacity of John Terry and Gary Cahill.
"At the moment I must say that is a decision I still have to make tomorrow morning," Wenger said.
"I try to use the best solution that gives us the most efficiency offensively.
"Every game is different and that is why I don't deny at all the quality of Walcott. I am very happy that he scored so many goals in so many starts. He shows as well that when he comes on, he can score as well, which he did in Zagreb."
