Alexandre Lacazette has become Arsenal's record signing after joining from Lyon in a deal which could be worth up to £53m.
The Frenchman was at Arsenal's training centre in Hertfordshire on Tuesday to have a medical before completing his record transfer from Lyon.
And on Wednesday afternoon the deal was completed, with Lacazette signing a five-year contract at the Emirates Stadium.
He will join up with his new team-mates for a pre-season tour to Australia and China next week.
A club statement on Wednesday evening read: 'Alexandre Lacazette has agreed to join us on a long-term contract, for an undisclosed fee.
'He is expected to travel with the tour party to Sydney this weekend and is likely to make his home debut in the Emirates Cup on July 29 or July 30.
'The deal is subject to the completion of regulatory processes.'
Arsenal manager Arsene 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.'

Lacazette's transfer will smash the Arsenal transfer record which stands at £42.5m for Mesut Ozil in 2013.
Lyon, his hometown club, will receive £46m with up to £7m more in add-ons depending on his success in north London.
His arrival could hasten the departure of his France team-mate Olivier Giroud who is wanted by Everton, West Ham and Marseille.
