New signing Edin Dzeko made his debut but it was partner Carlos Tevez [ Images ] who scored twice in a nervy 4-3 home win over Wolverhampton Wanderers that took Manchester City [ Images ] top of the Premier League on Saturday.

Dzeko, a 27 million pounds ($42.77 million) signing from VfL Wolfsburg, made a promising debut and set up City's third goal for Yaya Toure [ Images ].

It was Tevez who turned the match when he beat three defenders and finished calmly to put City 2-1 up early in the second half after Wolves had taken a surprise lead.

Tevez headed City's fourth but the hosts were hanging on desperately at the end after a Kevin Doyle penalty and a Ronald Zubar header made it 4-3 four minutes from time.

Chelsea [ Images ] struggled again but managed to beat Blackburn Rovers 2-0 at Stamford Bridge [ Images ] with second-half goals by Branislav Ivanovic [ Images ] and Nicolas Anelka [ Images ].

City return to the top on 45 points from 23 games, a point ahead of Manchester United [ Images ], who visit Tottenham Hotspur [ Images ] on Sunday and have three games in hand.

Arsenal [ Images ], who visit West Ham United later on Saturday are third on 40, Chelsea fourth on 38 and Spurs fifth on 36.
