Wayne Rooney's poor start as Birmingham manager continued as his side suffered a 3-1 defeat at Southampton yesterday.
First-half goals from Taylor Harwood-Bellis and Carlos Alcaraz put Saints on course and Adam Armstrong wrapped up victory with his eighth of the season after a reply from Blues substitute Jay Stansfield.
Rooney's side were short on luck - there was a suspicion of offside for Harwood-Bellis' goal and City had a strong penalty appeal turned down - but they have now lost all three since the former England and Manchester United striker controversially replaced John Eustace.
Elsewhere, Harry Winks scored his first goal for Leicester to hand the leaders a late 2-1 win at 10-man QPR.
The Foxes had been pegged back by Andre Dozzell after taking the lead through Stephy Mavididi on 30 minutes.
Dozzell turned villain when he was sent off for a second bookable offence following a tussle with Abdul Fatawu just before the hour and Winks took advantage with an 80th-minute winner.
QPR sacked boss Gareth Ainsworth in the wake of the defeat.
Third-placed Leeds got back to winning ways as they thrashed Huddersfield 4-1.
Dan James and Crysencio Summerville both scored twice in the first half as Daniel Farke's side impressed.
Michal Helik netted a consolation for the Terriers, who have won just one in seven under Darren Moore.
Preston's downturn in form continued as they lost 1-0 at Hull.
Jayden Philogene scored the only goal after 68 minutes, extending the Lancashire side's winless run to seven games.
Middlesbrough's six-game winning run came to an abrupt halt as Stoke claimed a 2-0 win at the Riverside Stadium.
Goals from Michael Rose and Mehdi Leris in the first half proved the difference, with Boro unable to get back into the game despite hitting the bar through Josh Coburn.
Sunderland claimed their first win in four games as they came from behind to beat Norwich 3-1 at the Stadium of Light.
Hwang Ui-jo opened the scoring for the Canaries after 23 minutes but the Black Cats were ahead by half-time after replies from Trai Hume and Dan Neil. Jack Clarke's penalty 10 minutes from time completed the job.
The defeat means Norwich ended October without a win and have lost seven of their last ten games to slide to 17th in the table.
Asked about his future after the defeat, under-pressure Norwich boss David Wagner told the EDP: "I understand the question, but this is not a question I can answer.
“These are situations you face as a manager, which you don't like, but these are challenges which are part of the manager's life.
"Obviously it's up to me to get this sorted, but how much time or if I get the time? As I said this is not the question for me.
“I know how this game is. I am part of it long enough. It hurts. I love my team, this football club and the community I live in. But we have not delivered the results.
“At the end of the day I'm a human like you. I like the praise and I don't like the criticism but I respect the criticism.
"I personally know exactly when it's right and when it isn't right. And at the minute, it's right, because we didn't collect points, and we didn't perform where we can do.”
Mileta Rajovic grabbed a last-minute equaliser as Watford snatched a 2-2 draw against Millwall at Vicarage Road.
Wes Harding had looked to have won it in the 85th minute for Millwall, who remain under the caretaker charge of Adam Barrett. The Hornets struck first in the game through Yaser Asprilla with Zian Flemming equalising.
A Perry Ng header and late Rubin Colwill effort handed Cardiff a 2-0 win over Bristol City and Swansea triumphed 1-0 at Blackburn with a Liam Cullen strike.
Bristol City parted company with boss Nigel Pearson after the defeat.
Finally, in today's lunchtime kick-off, Sheffield Wednesday got their first win of the season as they beat locals rivals Rotherham United 2-0 with both goals coming from ex-Miller Michael Smith.
They remain bottom of the table, eight points from safety.
