It was a relatively low-key affair as Spain's Primera Division made a number of deals as the European transfer window came to a close.
Mexico forward Giovani Dos Santos joined Racing Santander on loan from English side Tottenham, his third temporary move since arriving from Barcelona in 2008 following stints at second-tier clubs Ipswich and Galatasaray.
The 21-year-old Dos Santos had recently returned to Spurs, making five appearances in all competitions this season.
He was relegation-threatened Santander's only significant signing under new owner Ahsan Ali Syed, who watched his first game on Monday as his team drew 1-1 against Valencia in Spain's Primera Division.
Ali Syed had said Serbia striker Nicolas Zigic would be arriving for a third stint with Santander but that deal never went through.
American forward Jozy Altidore joined defending Turkish champion Bursaspor on loan from Villarreal for the rest of the season.
Altidore has appeared as a substitute in two league matches this season for Villarreal, who loaned Jefferson Montero to Levante on the last day of the January transfer window. Altidore's only goals this season were two against Poli Ejido in the fourth round of the Copa del Rey.
The Spanish league had said Altidore would be joining struggling Levante on loan but later retracted that announcement.
