Arsenal has signed 18-year-old Brazilian forward Gabriel Martinelli from Ituano Futebol Clube for an undisclosed fee, the Londoners announced on Tuesday

Martinelli scored 10 goals in 34 appearances for Sao Paulo-based club Ituano and was called up for a training camp with the senior Brazil squad ahead of the Copa America.

Martinelli becomes Arsenal’s first new recruit of the summer, while a reported £40 million ($50 million) bid from the Gunners for Wilfried Zaha has been rejected by Crystal Palace.

The Eagles, who sold right-back Aaron Wan-Bissaka for a deal worth up to £50 million to Manchester United earlier this week, are believed to value Zaha at £80 million.

However, Zaha’s brother has pleaded with Palace to let him join the club he supported as a boy.

Zaha is currently on international duty at the Africa Cup of Nations with Ivory Coast and scored in a 4-1 win over Namibia on Monday to help them reach the last 16.
