Joel Campbell's switch to Villareal is official.

Joel Campbell has sealed his loan move to La Liga side Villareal.

The Costa Rica international has joined until the end of the season, as part of the deal which will see Gabriel Paulista join the Gunners.

Villareal confirmed the transfer at the weekend on their official website, and he has been presented to the media today.

There were high hopes for Campbell this season at Arsenal, after the attacker played a key role in Greek side Olympiakos' title winning campaign, also scoring an impressive goal against Manchester United.

He also starred at the World Cup, netting against Uruguay, as Costa Rica surprisingly reached the quarter finals.

Disappointingly, he has been unable to break into the Gunners side this season, used sparingly, and the return of Theo Walcott from injury limits his chances further.

Campbell has previous experience of playing in La Liga, having spent a season with Real Betis.
