Arsenal is poised to sign 19-year-old Costa Rica striker Joel Campbell.

The Premier League club says on its website it has agreed terms with Costa Rican side Deportivo Saprissa and the transfer is ''subject to the completion of formal agreements and processes.''

Campbell represented Costa Rica at the recent Copa America and the Under-20 World Cup.

Arsenal manager Arsene Wenger says 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.''
