The Gunners icon believes the striker could find it difficult to adapt to the Premier League in his first few months at his new club
Arsenal's record signing Alexandre Lacazette will need time to get used to life in the Premier League, former Gunners star Robert Pires has warned.
The striker moved to the Emirates Stadium from Lyon this month for a reported fee of £52.7million, making him the club's most expensive player.
Lacazette scored on his debut in a 2-0 friendly win over Sydney FC, having hit 28 goals in 28 starts in Ligue 1 last season.
