Sunderland are on the brink of signing Fiorentina fullback Marcos Alonso.

The Daily Mail says Alonso is expected to fly to England today ahead of a January move to Sunderland.

The 22-year-old, formerly of Real Madrid, joined Fiorentina from Bolton Wanderers in the summer. The plan is for the Spaniard to join Gus Poyet's side on loan for the rest of the season after struggling for games with the Viola.
