Roy Keane stood down as manager of Sunderland on Thursday after deciding he was no longer the man to take the relegation-threatened club forward.First-team coach Ricky Sbragia will take over team affairs on an interim basis and will be assisted by reserve-team coach Neil Bailey and senior player Dwight Yorke in preparing the squad for Saturday’s trip to Manchester United.After 24 hours of intense speculation that the former United, Celtic and Ireland midfielder star was on the brink of quitting, the shock departure was confirmed in the wake of a meeting between the 37-year-old and the club’s board.In his first season in charge, Keane steered Sunderland from the Championship’s relegation zone to promotion to the Premier League as champions and Sunderland retained their top-flight status relatively comfortably last season.“I would like to thank my staff, players, Niall Quinn and in particular the fans for their support during my time at Sunderland, and I would like to wish the club every success in the future,” Keane said.Tevez scores fourTottenham maintained their League Cup defence on Wednesday by rallying to beat Watford 2-1, while Carlos Tevez scored four times to put Manchester United into the semi-finals with a 5-3 victory over Blackburn.Harry Redknapp, who won the FA Cup for Portsmouth in May, is just two matches from a Wembley final with Spurs after Darren Bent’s 76th-minute winner.
