Arsenal have the confirmed the signing of highly-rated Costa Rica forward Joel Campbell from Deportivo Saprissa.
The 19-year-old has been tracked by the Gunners for some time but Arsene Wenger was forced to play a waiting game to secure his signature until after he finished his involvement with his country at the Under-20 World Cup in Colombia.
Campbell already has six full international caps despite his relative young age and he becomes 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 straightaway, but he told the club's official website he is looking forward to developing under Wenger's tutelage.
He said: "It is a dream come true to play for such a big club in England and I want to do well for myself and Costa Rica. I am ready, I am very happy to be here and I want to focus on doing well for Arsenal.
"Arsene Wenger is a manager of immense quality.
"He knows how to use youngsters' ability.
"I have been watching Arsenal play since I was a kid and I took this decision because I know I have a possibility to become a better player here."
