clearly had the momentum but Robin van Persie's deflected free-kick earned a huge three points in the closing stages.
Did you know? Yaya Toure has committed his future to City by signing a four-year contract. The midfielder's future had been the subject of some debate following some quotes attributed to his agent in the media.
Opposition boss: Roberto Mancini believes he has been the top boss in the country in recent years and he has certainly ensured the Blues' trophy drought is very much a thing of the past. Securing the league title last year will ensure he goes down in City folklore and he is still hoping to land the FA Cup despite writing off any hopes of catching United in the table. The Italian always has to contend with intense scrutiny but there appears to be a general consensus that he is doing a good job.
Star man: City's squad contains many star names but Yaya Toure's new deal is a boost as the marauding midfielder has been a key figure since joining from Barcelona. Although he played at centre-back against the Reds in the Champions League final in Rome, the Ivorian has been most effective when pushing forward and his match-winning display at Newcastle in the penultimate fixture of last season was vital in in the title race.
Sub-plots: The derby game continues to grow in intensity following City's rise to prominence in terms of competing for the top honours. Carlos Tevez will line up against his former club again and Wayne Rooney aims to continue his remarkable goalscoring record against the Blues. Victory for Sir Alex's side would bring a record 20th title within sight.
