Arsenal boss Arsene Wenger was delighted with two-goal Cesc Fabregas after their victory over Middlesbrough.
Wenger said: "He gets sharper and sharper in every game. He was out for three months and you don't come back at your best straight away. But now he gets better in every game. Every player who plays in midfield, who thinks they are creative and offensive, needs to score goals. That happened to him today and that's important.
"Usually Fabregas plays deeper with Nasri higher. I wanted to test how it would work the other way round. It could be reiterated that we will do it again because it was quite convincing. But that is open; we have 48 hours to study that then make a decision."
