Arsenal have announced they have agreed terms to sign teenage striker Joel Campbell on a day when Cesc Fabregas stands on the brink of joining Barcelona.
Nineteen-year-old Campbell was in his country's squad for the recent Copa America and the Under-20 World Cup.
The Gunners, who at the same time insist a deal has yet to be agreed for the sale of Fabregas, revealed on Friday night the transfer is subject to the completion of 'formal agreements and processes'.
Manager Arsene Wenger told his club's official website: "Joel Campbell has already shown that he is a player with great ability, and has also performed well on the international stage at a young age.
"We look forward to the formalities of the transfer being completed and working with Joel when he joins us at Arsenal."
Campbell is predominantly left-footed and has made six full international appearances, scoring twice.
He scored on his debut in a 5-0 win over Cuba at this year's CONCACAF Gold Cup, helping his side to the competition's quarter-finals.
Campbell has had two seasons in his native Primera Division, where he played for Deportivo Saprissa and on loan at Puntarenas, making a total of eight league appearances.
