Arsenal forward Joel Campbell has joined Serie A newcomers Frosinone on a permanent deal.
The 26-year-old Costa Rica international signed for the Premier League club in August 2011, making 40 senior appearances in seven seasons.
He also had six loan spells - one each at Lorient, Olympiakos, Villarreal, Sporting Lisbon, and two at Real Betis, where he spent last season.
