"It was just instinct," said Wilshere. "It came off and it was a good finish from Chamakh. Playing with people like Cesc Fabregas makes it easy for you. He'll talk to you and talk you through games. We saw what he could do tonight.
"It is perfect, playing with Cesc and Alex [Song]. We move well and play well together. It was an open game and we showed we could score goals as well."
