Arsenal manager Arsene Wenger has described new signing Alexandre Lacazette as an "efficient finisher" and "strong character".
The Premier League club announced his arrival on Wednesday after agreeing a deal with Lyon thought to be a club-record fee of £52m.
Lacazette, who scored 37 goals in 45 appearances in all competitions last season, has penned a long-term deal at the Emirates.
Wenger believes that the forward's quality will help the club challenge for top honours.
"We are very happy to have Alexandre join our group," said the manager. "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."
Arsenal will compete in the Europa League in the 2017-18 campaign after falling to reach the Champions League places.
