Spanish defender Cuellar joins Sunderland

Spanish defender Carlos Cuellar has joined Sunderland on a two-year deal, the Premier League club said on their website on Monday.

The 30-year-old, a free agent after leaving Aston Villa last month, is reunited at Sunderland with his former manager Martin O'Neill.

Cuellar is ex-Villa boss O'Neill's first permanent signing since taking over at Sunderland midway through last season.
