On the game:
"It was a convincing performance and a strong result. I believe that we are on a strong run and it's down to us to be mentally at a level to maintain that run and keep the focus in every single game."
"We just need to keep winning games. We are Arsenal football club and if people don't expect us to be there or thereabouts, I think it's a bit disrespectful.
"We have faith in ourselves and if we keep getting results like today, we'll deserve to be up there.
"We're into December now and we know it's going to be tough, but today was a first step and we want to keep it going."
On Sanchez:
"I thought it took him a while mentally to get into the game, but he's a fighter, he's a winner, he's a classy player and he can give you something special.
"He has been exceptional. You don't find many players who can dribble that fast, who close down so quickly and have that short backlift that can surprise you. And he has a great technique as well."
"He gives you that speed in behind and he's one of those players, like Aguero, who you get the ball up to and they make things happen."
"He did that tonight, creating two of his goals himself and finishing them off brilliantly. That's what he gives you and it's great to have him in the team."
