Spanish midfielder Santi Cazorla signed with Villarreal after successfully completing a trial period, sources with the La Liga side told EFE Monday.

Cazorla, who was part of the Spain national team that won the 2008 and 2012 Euros, came to Villarreal's preseason camp to assess whether or not he could continue playing at the professional level after missing the better part of two seasons with injuries.

It was Villarreal that gave him his start as a professional player in 2003 and the club sees Cazorla's return as one of the most special signings in its history, the sources said.

Cazorla, 33, left Villarreal in 2011 and spent a year with Malaga before joining Premier League team Arsenal, where he scored 25 goals in 129 matches over six years.
