Arsenal made the most of Manchester City's defeat to extend their lead at the top of the Premier League table to eight points following a 2-0 win over rivals Tottenham on Sunday.
The Citizens had hoped to close the gap to table-toppers Arsenal to two points with a victory at rivals Manchester United on Saturday and it looked like Pep Guardiola's side were on course to make that happen, as they went ahead through Jack Grealish on the hour mark.
However, a controversial equaliser for Bruno Fernandes brought the Red Devils level before Marcus Rashford continued his fine scoring form, netting his eighth goal from his last seven appearances across all competitions, to secure the victory for Erik ten Hag's side.
That result gave the Gunners the opportunity to move eight points clear at the summit, and Mikel Arteta's men grabbed the chance with both hands as they picked up a 2-0 win at Tottenham in the North London derby on Sunday.
Spurs goalkeeper Hugo Lloris turned a deflected Bukayo Saka cross into his own net in the 14th minute before Martin Odegaard fired into the bottom-right corner from outside the area nine minutes before the break, giving the visitors a comfortable and deserved lead.
Arsenal managed to see out the victory in the second half to extend their advantage at the top, a result that moves the Gunners a step closer to a first title since 2003/04, while also ending an eight-game winless run at the home of their fierce rivals.
Arsenal knew the trip to Tottenham was the start of an important run of games for them and the fact they delivered when required will be a huge positive for Arteta, whose side are now favourites to win the title.
The Gunners outclassed Spurs and they will now be hoping to maintain their high standards when they welcome in-form Manchester United to the Emirates on 22nd January.
With nine points separating Arsenal and the Red Devils, the result of this upcoming clash could have a big impact on the overall outcome of the title race.
A win for the Gunners would further strengthen their hopes of landing the title, while a victory for Ten Hag's troops would move them into the title reckoning, for which they are currently on offer at 12/1.
Trips to Manchester City (FA Cup) and Everton loom for the Gunners, who then host Brentford and the Citizens in a stretch of matches that could see them pull away from the chasing pack or allow the gap at the top to be cut.
It seems like there is always a talking point when it comes to VAR every week and that was no different in the latest round of fixtures, as United were handed a controversial equaliser in the Manchester derby.
When the pass was played through to Rashford he was clearly in an offside position, but he didn't make contact with the ball and Fernandes ran through to curl in a lovely finish.
However, the England international certainly had a part to play in the move, making contact with the ball or not as he surely affected goalkeeper Ederson's thinking, and it remains a mystery as to how VAR overturned the original offside decision and awarded the goal.
VAR has been involved in big moments in the Premier League this season and it is incidents like the one on Saturday that could end up having a huge bearing on the overall outcome of the title race. City are now out to to successfully defend the title after their derby setback.
Although backed by mega-rich owners, nobody would have anticipated Newcastle to have improved as quickly as they have, but that is what is happening with the Magpies right now and a top-four finish is very much in their sights.
Eddie Howe's men weren't at their fluent best in Sunday's home clash against Fulham but they managed to take advantage of Aleksandar Mitrovic's double-hit penalty to snatch all three points, and they are now priced at to finish in the top four.
Sweden international Alexander Isak's 89th-minute strike sent St James' Park into raptures and ensured the north-east outfit would move back to third in the standings - a point behind Man City in second.
While a nine-point gap to Arsenal may be too much to pull back, a return to the Champions League is very much a possibility and one that the Geordie faithful have realistic ambitions of achieving.
It has been a torrid time for Chelsea manager Graham Potter over recent weeks but the pressure on his shoulders was eased slightly on Sunday, as his side beat Crystal Palace 1-0 at Stamford Bridge.
Although not the most accomplished performance, it was a victory nonetheless and one that will be welcomed by the former Brighton manager because of the grumblings from the crowd.
On another positive note for Chelsea, they also completed the signing of Mykhailo Mudryk and he was paraded on the pitch at half-time in that win over the Eagles.
While Sunday was all about the title race, Saturday's games had a relegation feel about them and Everton's Frank Lampard must be fearing for his job.
While life is tough for the Everton manager, the same could be said of West Ham boss David Moyes after his side suffered a 1-0 defeat to another struggling side, Wolverhampton Wanderers, at Molineux.
The gap between Southampton in 20th and Forest in 13th is currently five points and the battle to stay in the Premier League looks like it will go right down to the wire.
