The 18-year-old Brazilian attacker had a trial at Manchester United and trained but Barcelona but he is now bound for the Emirates
The Gunners have paid Ituano FC £6 million ($7.7m) for the 18-year-old forward, who has penned a “long-term” contract with the north London club. Martinelli is an unfamiliar face to the majority of Arsenal fans
Martinelli is one of the rising stars in Brazilian football, having enjoyed a fine start to his senior career with Ituano.
He first started playing with Corinthians’ futsal team at the age of just nine before joining Serie D team Ituano in 2015. He signed his first professional contract two years later.
He made his senior debut in March 2018, coming off the bench against Taboao da Serra at the age of 16 years and nine months, becoming the youngest player to debut for Ituano this century.
Arsenal believe Martinelli has the potential to go to the top, with head of international recruitment Francis Cagigao the driving force behind the deal.
Cagigao – known for his strong contacts in South America – then travelled to Brazil himself to watch the the talented forward on more than one occasion before finalising the transfer.
