Alexis Sanchez has been directly involved in eight goals in his past eight Premier League appearances (five goals, three assists)
Arsenal boss Arsene Wenger: "It was a mental test when we were at 1-1. We missed so many chances, so many opportunities, and I was worried we could lose - but we have shown great strength to bounce back.
"In the Premier League at 1-1 you can lose the game but it was about how we responded. Do we panic, give up, feel sorry for ourselves? We responded well and in the end it was a comfortable win.
On his introduction of Giroud, who then scored twice in the next seven minutes, Wenger added: "The manager has an easy credit when he has quality players on the bench and you don't need to be a special manager to make this decision. It was 1-1 and we had Giroud on the bench."
