Arsenal striker Joel Campbell has joined Sporting CP on-loan for the season.

The 24-year-old scored four times in 30 first-team appearances last year, having joined the club in 2011 and enjoying previous loan spells at Lorient, Real Betis, Olympiacos and Villarreal.

The forward will be hoping he can help the Portugese side win the Primeira after their second-placed finish last year and gain further Champions League experience.

The move is subject to international clearance and formal ratification.
