Joel Campbell: Arsenal forward joins Villarreal on loan

Joel Campbell has made four appearances as a substitute in the Premier League this season

Arsenal striker Joel Campbell has joined Spanish club Villarreal on loan for the rest of the season.

The 22-year-old's move is part of the deal that will see defender Gabriel Paulista move to the Premier League club for £15m, according to Villarreal.

Costa Rica international Campbell has made 10 appearances for Arsenal this season but has not scored a goal.

He spent last season on loan with Greek club Olympiakos and played for his country at the 2014 World Cup.
