Arsenal forward Gabriel Martinelli has signed a “long-term” contract extension, the Premier League leaders said Friday. The 21-year-old Brazil international has scored seven goals this season to boost Arsenals title bid in his fourth season in north London. The club did not specify the length of the deal but manager Mikel Arteta called it “a new long-term contract.” “Gabi is still very young, so we know theres still much more to come from him and its great that well be on this journey together,” Arteta said in the clubs announcement. Martinelli was not quoted in the announcement. The forward has started all 19 league games this season. He has made 111 appearances in his Arsenal career since signing from Sao Paulo club Ituano in July 2019.
