Carlos Tevez scored for the first time in 11 months as Manchester City sparked back into life to keep their faint title hopes alive with a 4-0 win over West Brom.
Sergio Aguero struck twice and David Silva was on target in a routine defeat of West Brom as City, perhaps belatedly, showed why they were once firm favourites for the Barclays Premier League crown.
Manchester United's 1-0 defeat at Wigan meant the gap at the top was cut to five points, and with a derby to come the game may not yet be up, but it could still be too little too late.
Tevez's first start since his much-publicised dispute with the club gave the side a different look.
And they took just six minutes to take the lead as Aguero collected the ball midway inside the West Brom half and ran diagonally towards goal before lashing in a low shot past Ben Foster from 25 yards.
City looked back to their best and Micah Richards should have doubled the lead just after the half hour as he timed his run onto Tevez's pass perfectly and cut back to shoot past Foster, but Craig Dawson blocked on the line.
Samir Nasri volleyed wide from a Silva cross soon after the restart and City really started to lift themselves as news filtered through to the crowd that United had fallen behind at Wigan.
City's second came in the 54th minute as Nasri seized on a poor clearance and slipped in Aguero to slide the ball past Foster.
Tevez claimed his goal on the hour, the Argentinian finding himself in the right place to tuck home an Aguero cut-back from a Nasri pass.
A fourth goal duly arrived after Jonas Olsson conceded possession to Aguero and he quickly released Silva, who took the ball in his stride and sublimely chipped the advancing Foster.
