The Costa Rican has move to El Madrigal as part of the deal that sees Gabirl Paulista arrive at club.
This week Arsenal added to their defensive area with the signature of Brazilian centre-back Gabriel Paulista from Villarreal.
The defender arrived in a reported £11.2 million deal, according to the BBC, but that was not all that exchanged hands. Arsenal also sent the Yellow Submarine Costa Rican striker Joel Campbell on loan.
The striker signed a new long-term deal at the club before being granted the loan move, in order to get regular first-team football.
He has now been speaking about his move to the La Liga club, with quotes published by Diario AS. He revealed his love for playing in Spain and on how an Arsenal team-mate helped him make the decision:
"I’m ready to work hard so that things work out for the best. My head is in Villarreal and I’m determined to prove my worth here at this club.
"It certainly is [special to play in Spain], I was fortunate to have played with Real Betis and now I get the opportunity again at Villarreal.
"Santi Cazorla is a great player; he told me that how I’d find the club and that Villarreal is one big family."
Cazorla spent eight years at Villarreal, including a season co-owned by Recreativo Huelva, so his advice would have been wisely sought.
Campbell had an excellent World Cup and also shone in a recent loan spell at Olympiakos. However he has struggled to find regular first-team football at Arsenal this season and is now embarking on his fourth loan spell away from the club, following similar deals at the Greek side, Lorient and Real Betis.
