Watford's bid for a quick return to the Premier League remains firmly on course after a 3-1 win against Norwich on Tuesday.
Adrian Boothroyd's side were relegated last season, but they moved eight points clear at the top of the Championship thanks to strikes from Darius Henderson, Marlon King and a David Marshall own goal.
It was top versus bottom at Carrow Road and the disparity between the teams was clear as Watford left new Norwich boss Glenn Roeder still searching for his first victory.
Henderson opened the scoring in the 36th minute, slotting home his ninth goal of the season from close range. The Hornets increased their lead two minutes before half time when Norwich goalkeeper Marshall inadvertently turned in Adrian Mariappa's header.
Lee Croft reduced the deficit in the 65th minute but Norwich are now without a win in 11 games, but King settled the game in the 88th minute.
Charlton striker Chris Iwelumo shattered Bristol City's long unbeaten home record with a stoppage time goal that clinched a 1-0 win at Ashton Gate. Iwelumo had scored a last-minute winner at Southampton on Saturday and he repeated the trick to hand City a first home defeat since March.
Alan Pardew's side had won just one of their last five games but they had the better of the game before snatching the points when Iwelumo headed in Andy Reid's cross for his sixth goal of the season.
West Bromwich Albion moved into second place, but they finished disappointed after Steve Watson's late goal earned a 1-1 for Sheffield Wednesday at the Hawthorns.
