Struggling Wigan breathed life into the Premier League title race with a stunning 1-0 upset of Manchester United on Wednesday as Manchester City romped to a 4-0 win over West Bromwich Albion.
Just days after United looked to have assured themselves of a 20th league crown by opening up an eight-point lead over City, Shaun Maloney's 50th-minute winner for Wigan suggested the title race may yet have more twists in store.
City's emphatic win over West Brom at Eastlands reduced United's lead at the top to five points with five games remaining, meaning Sir Alex Ferguson's side have little margin for error in their remaining fixtures.
United -- who must travel to City on April 30 -- looked sluggish throughout as Wigan claimed a precious three points that lifted them out of the relegation zone at the expense of Bolton.
United were fortunate not to fall behind after Wigan appeared to have taken the lead through Victor Moses midway through the first half, only for the goal to be ruled out for a foul on United goalkeeper David de Gea.
But United were not so fortunate on 50 minutes when Wigan took the lead with a magical strike from Maloney, curling a superb shot beyond De Gea after a clever short corner routine.
Meanwhile City bounced back from the disappointment of Sunday's 1-0 defeat at Arsenal with a drubbing of West Bromwich Albion which included a goal for returning bad-boy Carlos Tevez.
Sergio Aguero opened the scoring for City after only six minutes, sweeping in past Ben Foster after evading the attentions of Keith Andrews.
Aguero then grabbed his second shortly after half-time, applying the finishing touch after neat inter-play between David Silva and Samir Nasri.
