Manchester: A sparkling two-goal display by Carlos Tevez overshadowed a promising debut by Edin Dzeko as Manchester City claimed a nervy 4-3 win over Wolverhampton Wanderers to go top of the Premier League.
Dzeko, a 27 million pounds buy from VfL Wolfsburg, made a good first impression as City led 4-1 but they were hanging on at the end against the doughty visitors.
Chelsea struggled again but managed to beat Blackburn Rovers 2-0 at Stamford Bridge with second-half goals by Branislav Ivanovic and Nicolas Anelka. City`s victory takes them back to the top on 45 points from 23 games, a point ahead of Manchester United, who visit Tottenham Hotspur on Sunday and have three games in hand.
Arsenal, who visit West Ham United later on Saturday (1730 GMT) are third on 40, Chelsea fourth on 38 and Spurs fifth on 36.
Peter Odemwingie scored twice, including the winner three minutes from time, as West Bromwich Albion beat Blackpool 3-2, Stoke City beat Bolton Wanderers 2-0 while Wigan Athletic drew 1-1 at home with Fulham.
Wolves, who beat City at Molineux in October and have taken the scalps of Liverpool and Chelsea in recent weeks, again took the game to their big-name opponents and grabbed a deserved lead after 12 minutes when Nenad Milijas scored on the rebound.
Wolves should have had a second but City rode their luck and levelled five minutes before halftime when a Kolo Toure shot was deflected by David Jones and into the net.
