Arsenal's Campbell joins Villarreal on loan

LONDON (Reuters) - Arsenal forward Joel Campbell has joined Villarreal on loan for the rest of the season, the Spanish club said on Tuesday.

The Costa Rican's move to Spain is part of a deal in which Arsenal are set to sign Villarreal's Brazilian defender Gabriel Paulista, who has passed a medical in London, British media reported.

"Thanks to the whole family of Arsenal for their messages. I hope to make them proud," Campbell said on Twitter alongside a photograph of him wearing a Villarreal scarf.

The 24-year-old Paulista is poised to become Arsenal's second signing of the January transfer window after Polish teenager Krystian Bielik.
