Arsenal boss Arsene Wenger says the signing of Alexis Sanchez is proving money well spent.

Alexis arrived in the summer from Barcelona.

"What you want when you invest so much money is to get paid back. When I bought Sanchez I thought he can play on the right, on the left, through the middle," said Wenger. "That was an important quality.

"Secondly, I wanted someone who has a fighting spirit in the Premier League, to adapt, and to give something to the team on that front. That was needed - someone to say, 'Come on, I'm ready for a fight'.

"Thirdly, a guy who has a good combination of running in behind and who can dribble as well. On all of that, I was not disappointed. I was extremely happy."
