Alexandre Lacazette agreed to join us on a long-term contract for an undisclosed fee in July 2017.
The 26 year-old French forward arrived in north London as the most prolific striker in France over the previous four seasons with 91 league goals. He scored 28 times in just 30 games in the 2016/17 season and averaged close to a goal every two games for Lyon, scoring 100 times in 203 league matches.
Lacazette is considered to be adept across the front line but found his best form in a central role for his hometown club in Ligue 1.
In 2010, he was part of the France Under-19 squad - alongside Francis Coquelin - that won the Under-19 European Championship. France faced Spain in the final, winning 2-1 in a match which saw Alexandre score the winning goal with just five minutes left to play.
His breakthrough to the Lyon first team continued the following season and by 2011 he had become a regular fixture for the Ligue 1 outfit.
Following the 2014/15 season Lacazette was awarded the Ligue 1 Player of the Year award, as well as winning the division's top goalscorer prize after scoring 27 times in 33 games.
Alexandre was named in the Ligue 1 Team of the Year three times during his time in France.
Speaking after Lacazette's signing, Arsène 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."
