Huddersfield Town have signed Spanish midfielder Alex Vallejo.
The 28-year-old was a free agent after leaving Fuenlabrada.
Huddersfield Town's Head of Football Operations Leigh Bromby explained: "Álex is well known to Carlos and is a player we have discussed and watched together at length ahead of completing the signing.
"We know the frequency of our league games between now and the end of the season is more intense than ever, and Álex adds depth in a very important position in our team and squad.
"I spoke with him on several occasions and he is passionate about this chance to play in England. He now has the opportunity to impress everyone between now and the end of the season."
