Sunderland signs Alonso on loan

Sunderland, England (SportsNetwork.com) - Sunderland have completed a deal to sign defender Marcos Alonso from Fiorentina on loan for the remainder of the season, the Premier League club announced on Monday.

Alonso had a medical exam at the Stadium of Light and will officially join the Black Cats when the transfer window opens in January.

Alonso, 23, left Bolton for Fiorentina in May, and is Gus Poyet's first signing as Sunderland manager.

"I was looking for a player in that position on the left side and I hope he will help us," Poyet said. "I am delighted that everything is agreed."

Alonso began his career at Real Madrid, where he made just once appearance for the club's first team after a long stint with the club's 'B' team.

Sunderland sit at the bottom of the table on 14 points. The Black Cats will look to take three points when they host Aston Villa on New Year's Day.
