Arsenal striker Joel Campbell has joined Sporting on a season-long loan, the Portuguese club said on Sunday.

The 24-year-old Costa Rica international, who scored three goals in 19 Premier League games for the Gunners last season, is a versatile player who can play across the front line.

It is his fifth loan since joining Arsenal, following earlier spells at Lorient, Real Betis, Olympiacos and Villarreal.

Arsenal, who have taken just one point from their opening two Premier League games, are expected to sign a new striker before the close of the transfer window at the end of the month.
