The Gunners have won seven of their last eight in all competitions and after beating Norwich City 2-1 on the weekend, Walcott feels the North Londoners are in good shape to add to their eight Group F points in the Champions League especially if skipper Robin van Persie can continue his stellar form.
“We are playing beautiful football at this moment in time,” Walcott said.
“Robin up front makes our jobs so much easier. He’s one of the best strikers in the world right now.
“We can keep on winning.”
Arsenal top their group after four matches with Dortmund sitting third with four points from their four outings.
