Manchester City ensured Sunderlandâ€™s poor run of form continued with a 5-0 thumping at Eastlands further consolidating City in the top four placings.
Sunderland have just one point from their last six games and have now failed to score in their last four outings.
Fortunately the points accumulated in the earlier part of the campaign should see them sucked into a relegation battle because on this performance they are ripe for a relegation place.
The Black Cats then found themselves two down as Carlos Tevez was brought down by Phil Bardsley and the Argentinean converted the resulting penalty.
Steve Bruceâ€™s team tried to rally but for all their possession lacked the killer ball to worry the City defence.
Any hopes of a second half rally by the visitorâ€™s vanished just after the hour mark as City hit three in ten minutes.
David Silva made it three after Mario Balotelliâ€™s initial shot had only been parried by Simon Mignolet. Patrick Vieira had literally only just come on as a substitute when his first touch from an Aleksandar Kolarov corner found the back of the net.
Sunderlandâ€™s miserable afternoon ended when Toure made the most of an awful Lee Cattermole back pass to make it five.
Roberto Mancini now has the satisfaction of seeing his City team sit in third place in the Premiership after an emphatic performance against admittedly poor opposition.
