Edin Dzeko thinks Tuesday's derby demolition at Old Trafford proves Manchester City are kings of Manchester.
Dzeko scored two goals - the first after just 43 seconds - and Yaya Toure also found the net in a comfortable 3-0 Barclays Premier League win for City over their bitter rivals Manchester United.
City now lead United by 15 points - and they have two games in hand over their neighbours.
The Blues have won on their last three visits to Old Trafford - by an aggregate score of 11-2 - so there is no wonder Dzeko feels City have the wood over their rivals.
"It's always good to win in a derby, especially when you win it like we did," Dzeko told City TV.
"It was great for the fans to be here and to celebrate again.
"We are happy for them because a derby is something special and we showed them again who is the boss in the city.
"We could have scored another two in the first 30 minutes but we controlled the game, it was all about us.
"It could have been more but we were happy with 3-0."
City overpowered United in midfield and they had no answer to the goalscoring abilities of Dzeko, who took his tally to 20 for the season.
Although United are nowhere near as strong this year as they were under Sir Alex Ferguson, the value of the win for Manuel Pellegrini's side cannot be under-estimated.
Beating their big rivals on their home turf in such an easy manner is still regarded as special by their players and fans, as captain Vincent Kompany acknowledged.
"Every single win at Old Trafford is one of (those) things that goes down in history," the Belgian said.
"We look forward to those kind of games so when you win them it's special.
"The 6-1 (in 2011) was a very special result and it was against a Manchester United who was competing for the league at that time.
"They were special results but (Tuesday) was important because we are trying to win the league so it's always a great feeling, but obviously we had to win today."
While United lick their wounds after a sixth home league defeat, City turn their focus on to Saturday's game at Arsenal, which could have a big bearing on the title race.
If City win their two games in hand over current leaders Chelsea, they will lead Jose Mourinho's men by three points.
City arguably have the easiest run-in of all three title contenders, but Kompany insists there is still a lot of work for he and his team-mates to do before they secure the league title.
"(The derby win) is just one little step," the City skipper said.
"The other teams are still very good. As long as we don't have the points, I don't consider ourselves there yet.
"We have momentum, but who doesn't have momentum at the moment? Liverpool have momentum and Chelsea have momentum, too."
Unlike United, City have enjoyed a good record against the top six sides this year, and Kompany thinks his team-mates will be ready for the challenge of facing Arsene Wenger's team, who bowed out of the title race with a 2-2 draw against Swansea on Tuesday.
"We have a game against Arsenal and that's good in a way because you don't have to make a big effort to get the lads focused again," the centre-back added.
