Wenger said: "We are very happy to have Alexandre join our group. He has shown over a number of years that he can score goals and that he is a very efficient finisher.

"As well, he has very interesting technical qualities and a strong character. So he is a guy who is a great addition for us, and someone who will help us challenge at the top level this season."

The 26-year-old is expected to make it straight into the Arsenal set up in the coming season.
