(Reuters) - Middlesbrough face a "must-win" match when they host fellow Premier League relegation candidate Sunderland in Wednesday's Tees-Wear derby, striker Alvaro Negredo has said.
The 31-year-old Spain international, who has played derbies in Seville, Manchester and Valencia during his career, believes Middlesbrough have an opportunity to end their 16-game winless run in the league.
