Xemi Fernandez has been allowed to leave Oxford United by mutual consent.
The midfielder joined the U’s last summer as a free agent from Barcelona B but has struggled to hold down a place in the first-team.
Xemi, 22, made only four starts in League One, his last appearance coming in Oxford’s 7-0 defeat to Wigan in December.
“It hasn’t worked out here and I’m sad to be leaving because it is a fantastic club,” the Spaniard said.
“But at the same time I want to be playing football and that means a new adventure for me elsewhere, which is exciting.”
Meanwhile, Sky Sports News understands Oxford have turned down three bids from Preston for midfielder Ryan Ledson.
Sky Sports also reported on Tuesday the club have enquired about re-signing Marvin Johnson on loan from Middlesbrough.
The 27-year-old winger, who joined Boro on Deadline Day in the last transfer window, has been told he has no future under Tony Pulis at the Riverside.
