I was at the 17th Jose Mourinho v Pep Guardiola clash on Saturday - and the first as a Manchester derby. The last was Bayern v Chelsea in the Super Cup in 2013. It was Pep's ninth win (including that shoot-out win), while Jose has won three and there have been five draws.
City have taken 13 points from their last six trips to Old Trafford. Man Utd went behind for the first time this season and the goal that put them behind from Kevin De Bruyne was the 100th league goal that City have scored away to United in history.
Kelechi Iheanacho became the youngest City player to score in a Premier League derby. Marcus Rashford scored the winner in the previous derby and is the youngest Premier League derby scorer overall. Mario Balotelli was the previous youngest for City, while Wayne Rooney was younger than Iheanacho when he scored his first derby goal.
Despite the defeat, Mourinho still has the satisfaction of being the only manager to finish above Guardiola in his seven seasons as a manager - as his Real Madrid side finished above Barcelona in 2011/12.
Has any team scored more Premier League goals than Liverpool in 2016? Ben R
Martin says: No, they have not! Jurgen Klopp's men lead the way with 50 goals in the league for the year and reached that total when they put four past champions Leicester on Saturday.
And the top scorers will face the joint second-top scorers on Friday Night Football this week as Chelsea host Liverpool at Stamford Bridge, so hopefully there will be plenty of goals in the match I'm commentating on!
Chelsea, along with Manchester City, have managed 45 goals in 2016. Both scored twice at the weekend, but it was City who maintained their 100% start to the campaign, thanks to the derby win over neighbours United.
Antonio Conte had to make do with a point, as Chelsea let slip a one-goal advantage, before eventually coming from behind to salvage a 2-2 draw.
Tottenham are fourth with 43 goals, thanks in part to their four-goal haul against Stoke on Saturday, and West Ham are one behind on 42.
West Brom have scored the fewest goals (18) of a club to be in the Premier League throughout the whole of 2016, Crystal Palace have netted 19 and Watford and Stoke have both managed 23 so far.
Santi Cazorla's past seven Premier League goals for Arsenal have all been penalties - is that a record? Gooner1983
Martin says: Should Santi Cazorla's next goal come from a penalty, he will become the first player to score eight goals in a row just from spot-kicks in the history of the Premier League.
The Arsenal midfielder's last seven goals have all come from 12 yards, equalling the same record of Danny Murphy, Jan Molby and former team-mate Mikel Arteta.
Cazorla last scored from open play in the Premier League during a 4-1 victory over Newcastle in December 2014, netting the second of the game for Arsenal before completing the scoring with a penalty late on.
The Spaniard then slotted a further four penalties that season, failed to score in 2015/16, and has struck twice in the last two games from the spot - including the late winner against Southampton on Saturday. He might have already broken the record had he converted the penalty he took against West Brom in November 2015.
Murphy's record came to an end after netting from open play against Manchester United for Fulham in 2010, while neither Molby nor Arteta ever scored again after scoring the final penalties of their seven-goal run. Therefore their last seven league goals were all penalties.
Leicester let in four goals on Saturday. Is that the first time a defending champion team has done that? Paddy
Martin says: No, the Foxes join the likes of Blackburn, Manchester United, Arsenal and Manchester City to all be in possession of the Premier League crown, but still show defensive frailties.
Blackburn became the first defending champions to do so in December 1995 when they were thumped 5-0 at Coventry, while United repeated that feat as they went down at Newcastle the following year.
Who can forget that infamous game in which Manchester United were beaten 6-3 by Southampton at The Dell in 1996?
The Red Devils were also thumped 5-0 by Chelsea three years later in 1999, 4-3 at Newcastle in September 2001 and 4-1 by rivals Manchester City in March 2004.
Arsenal, meanwhile, conceded four against Tottenham in November 2004 but actually won the game 5-4, before losing 4-2 at home to Manchester United three months later.
Ferguson's side were again on the end of a few thumpings as they were beaten 4-1 by Liverpool in March 2009, hammered 6-1 in the derby by Manchester City in 2011 - the first time they had conceded that number of goals at home since 1930 - and drew 4-4 with Everton at Old Trafford in 2012.
David Moyes' Manchester United suffered a 4-1 defeat at rivals Manchester City in September 2013, before United got some revenge with a 4-2 win over City in April 2015.
One I particularly remember from the old First Division came in August 1989 with Arsenal starting their campaign as champions losing 4-1 to Manchester United at Old Trafford - a match I was able to commentate on because my daughter Jenny, who was due on the day of the match, arrived eight days early. Bless her...
Hull have named an unchanged starting XI in their first four games. Has that ever happened before in the Premier League?
Martin says: Mike Phelan has named an unchanged Tigers side in their first four Premier League games this season, helping them to an impressive tally of seven points so far, but eight teams in history have gone longer without changing their side.
Hull team in every game this season: Eldin Jakupovic, Ahmed Elmohamady, Curtis Davies, Jake Livermore, Andrew Robertson, Samuel Clucas, Robert Snodgrass, Tom Huddlestone, David Meyler, Adama Diomande, Abel Hernandez
In the first Premier League season in 1992/93, Leeds named the same XI for their first seven games of the season, with Howard Wilkinson finally making two changes after a 2-0 defeat at Manchester United.
Aston Villa also named the same starting XI for the first seven games of the 2008/09 season, which is remarkable for a side in the 21st century.
Leeds (1992/93 unchanged XI): John Lukic, Chris Fairclough, Jon Newsome, Chris Whyte, Gary Speed, Tony Dorigo, David Batty, Gary McAllister, Eric Cantona, Lee Chapman, Rodney Wallace
Aston Villa (2008/09 unchanged XI): Brad Friedel, Luke Young, Martin Laursen, Curtis Davies, Nicky Shorey, Stilyan Petrov, Nigel Reo-Coker, Gareth Barry, Ashley Young, John Carew, Gabby Agbonlahor
Tottenham and Liverpool made no changes for the first six games of the 1994/95 and 1996/97 seasons respectively.
Should Hull name the same XI against Arsenal this weekend, they will go level with Ipswich Town (1994/95), Norwich City (1993/94), Tottenham (1993/94) and Crystal Palace (1997/98).i
Hull's team selection was partly caused by the financial situation at the club - though they have now recruited players that will be pushing for starting places.
It's clear from these figures that football has become more of a squad game and managers are aware of the values of rotation. Plus the transfer system was changed to include transfer windows and recruitment has seen players moving in and out after the start of the season.
