Two new managers, Manuel Pellegrini for Manchester City and David Moyes for Manchester United will remember their first experience in the Manchester derby very differently.
Pellegrini saw his star striker Sergio Aguero boss the game from the front, using his speed and skill to fire home two goals on the way to a 4-1 victory for the home side.
Midfielders Yaya Toure and Samir Nasri also provided goals for City and were huge parts of pressing the attack and not allowing United to find a way back into the game.
One of City's offseason additions, Alvaro Negredo was a handful for the United backline and although he didn't find the score sheet was influential throughout the contest.
"It's an important game for the team," said Pellegrini. "And for the fans they will be happy for the month now."
Though they have looked uneven at times to start the season, the victory over United moves City two points shy of the top of the table.
Moyes was forced to play the game without his number one offensive weapon when Robin van Persie was ruled out of the game with a groin injury.
His side was under the gun from the start of the game and had trouble dealing with the City attack immediately.
They held out for the majority of the opening half and looked as though they were going to trail only 1-0 at the interval when Toure scored just before the break.
Five minutes into the second half the advantage was doubled and the game was over.
Wayne Rooney, who was United's best player during the match, scored a beautiful free-kick goal in the 87th minute to get his team on the board.
"It's horrible to lose the derby, it's always horrible. It's worse when you lose in this way," said United captain Nemanja Vidic.
Moyes can take heart in the fact that legendary former United manager Sir Alex Ferguson was beaten 5-1 at Maine Road in his first Manchester Derby.
"I've made them aware of what I think," said Moyes when asked what he told the team.
The first axe of the season has fallen as Sunderland has sacked manager Paolo Di Canio after a winless start to the season that has seen them pick up only one point.
"The club would like to place on record its thanks to Paolo and his staff and wishes them well for the future," said Sunderland in a statement.
Despite helping the team avoid relegation last season, Di Canio remained a controversial appointment for Sunderland and its fans.
Di Canio had already been fined £8,000 for an outburst at a referee that saw him sent off.
Kevin Ball, a former Sunderland captain, has been put in temporary charge, with a League Cup game on Tuesday.
North London rules the top of the table as both Arsenal and Tottenham are on 12 points, two points clear of Manchester City, Chelsea and Liverpool.
Mesut Ozil was brilliant again for the Gunners as they rode to a 3-1 victory over Stoke City at the Emirates Stadium.
He had a hand in all three goals and was credited with two assists for his efforts.
Aaron Ramsey fired home the rebound of an Ozil free-kick in the fifth minute, Per Mertesacker converted an Ozil corner in the 36th and Bacary Sagna headed home an Ozil free-kick in the 72nd.
"The only thing of our position at the moment is that we are in a position where we can focus on improvement in a stable environment, so that's a good basis," said Arsenal manager Arsene Wenger.
Meanwhile Spurs, courtesy of an injury time winner from Paulinho, claimed a 1-0 victory over Cardiff City.
Tottenham dominated the contest with little to no push back from their opponents but it looked as though they were going to have to settle for just a single point.
With time winding down, Erik Lamela found Paulinho who tapped home the winning marker.
"We played so much football it would have been unfair to leave here with only one point," said Tottenham manager Andre Villas-Boas.
Other winners included: Chelsea, Everton, West Bromwich Albion, Hull City, Southampton, Aston Villa and Swansea City.
