Gunners sign 19-year-old Costa Rican starlet
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 U20 World Cup in Colombia.
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.
