"Proud to be blue, proud to be Al Hilal," said Martinelli during an unveiling video on his new club's social media channels.

He will join Ollie Watkins at Al Hilal after the England striker left Aston Villa in a deal worth an estimated £51 million.

Martinelli's departure comes after Arsenal sold fellow left-sided forward Leandro Trossard to Besiktas.

Martinelli made 53 appearances in all competitions last season, scoring 11 goals, as the Gunners won the top-flight title for the first time since 2004.

His nearly 300 games for Arsenal, including 62 goals, also saw him involved in their 2020 FA Cup and 2023 Community Shield successes.
