Arsenal have signed Costa Rica forward Joel Campbell from Deportivo Saprissa. The Gunners have confirmed the signing of the youngster on their website.
Campbell, 19, had been linked with a move to the Emirates for some time and has now completed his transfer after representing Costa Rica the the Under-20 World Cup in Colombia.
Despite his age Campbell already has six full international caps and becomes Arsene Wenger's fourth summer signing following the acquisitions of young defender Carl Jenkinson, Lille forward Gervinho and Southampton starlet Alex Oxlade-Chamberlain.
Campbell is not expected to feature for the Arsenal first team straight away, but he told the club's official website he is looking forward to developing under Wenger's tutelage.
