(Reuters) - Gus Poyet has threatened to walk away from Sunderland if he senses his players have given up fighting for their Premier League survival.
Monday's 2-1 defeat by West Ham United, their 17th loss of a season that has seen them firmly camped in the relegation zone for much of it, leaves them in 19th place with 25 points, four behind West Bromwich Albion in the relative safety of the 17th position.
