Birmingham City have signed Spanish international midfielder Borja Oubina Melendez - who is known as Oubina - on a season-long loan from Celta Vigo.
Oubina wanted to leave Celta Vigo following their relegation
The 25-year-old had asked to leave following Celta's relegation, and joined the Blues just before the transfer window closed on Friday.
"I would have liked Celta to transfer me and not go out on loan, but the club didn't want that," he said.
However, Birmingham have the option of making the move permanent next summer.
