Arsenal dropped points in the title race on a busy Saturday in the Premier League, denied by an Ivan Toney equaliser as Brentford drew 1-1 at Emirates Stadium.
Mikel Arteta's had a better day of it than north London rivals Tottenham, though, as Spurs were thrashed 4-1 at Leicester City, despite taking an early lead.
Elsewhere, Chelsea were denied a win at West Ham after Emerson Palmieri equalised Joao Felix's first goal of his loan spell from Atletico Madrid.
Southampton's woes continued as they were beaten 2-1 at home against Wolves, despite taking the lead and having a man advantage for over an hour after Mario Lemina was sent off for the visitors.
Newcastle United's run of draws continued as they were held 1-1 at Bournemouth, while Crystal Palace and Brighton and Hove Albion also could not be separated, and Fulham beat Nottingham Forest 2-0 at Craven Cottage.
Here, Stats Perform looks at Saturday's biggest games, with the guidance of Opta data.
West Ham 1-1 Chelsea: Blues struggle to handle Hammers
Graham Potter's Chelsea were left frustrated after a late claim for handball was denied at London Stadium, and this draw was the first in nine Premier League encounters between West Ham and Chelsea since a 0-0 in September 2018.
The Blues have drawn three consecutive Premier League matches for the first time since February 2012, and remarkably, there were no shots on target in the second half from either side, being just the second Premier League match where that has occurred this season after Southampton v Nottingham Forest in January.
Emerson became the first former Chelsea player to score his first Premier League goal for a club against the Blues since Frank Lampard for Manchester City in September 2014.
On his return from suspension, Joao Felix became the 12th different player to score for Chelsea in the Premier League this season, with no side having had more in 2022-23 (excluding own goals), which perhaps is not a surprise when you consider the number of players they now have.
Arsenal 1-1 Brentford: Toney time dents Gunners' title push
It seemed like business as usual when Leandro Trossard gave the hosts the lead, but this ended up being the first time Arsenal had failed to win a Premier League home game in which they scored first since January 2022. They had won 10 in a row at Emirates Stadium when opening the scoring before this game.
Brentford showed great resilience and have now scored 15 goals from set-pieces in the Premier League this season, with no side netting more (including penalties).
That could also be something for Arsenal to work on, as each of the last three Premier League goals the league leaders have conceded have come from headers, despite not conceding any beforehand this season.
Only Harry Kane (nine) has found the net away from home more often in the Premier League this season than Brentford striker Toney (seven), whose equaliser broke Gunners hearts.
Leicester City 4-1 Tottenham: Lloris-less Spurs hammered by Foxes
A high-scoring game was hardly a shock at King Power Stadium. There have been 128 goals scored in 34 Premier League matches between Leicester and Tottenham, with the average of 3.8 per game the highest such ratio among fixtures to be played more than 20 times in the competition.
Spurs, who were without injured goalkeeper Hugo Lloris, have lost two of their last three away games in the Premier League (W1), conceding four goals in each defeat, having only lost two of their previous 14 such games beforehand (W7 D5). The other recent heavy loss was 4-2 at Manchester City.
Despite having a disappointing campaign so far, Leicester here became the first team in Premier League history to score three first-half goals in back-to-back matches when conceding first in each game, having also done so at Aston Villa last time out.
Leicester's James Maddison, who was linked with a move to Antonio Conte's Spurs this week, scored and had an assist. Maddison has been directly involved in 11 goals in his last 10 Premier League starts (seven goals, four assists), scoring in each of his last three league appearances against Spurs.
Southampton 1-2 Wolves: Jones under pressure as Saints lose to 10 men
Head coach Nathan Jones is not the first Jones to struggle at Southampton. Saints have lost five consecutive Premier League home games for the first time since April-August 1998, when they were under the leadership of Dave Jones.
Wolves fought from a goal and a man down to win against their favourite Premier League opposition, having won each of their last five meetings, the first time they have ever been victorious in five consecutive games against a specific opponent in the competition.
It is clear where a big problem lies for Saints, having only kept one clean sheet in their last 28 Premier League matches (1-0 v Bournemouth in October).
Jan Bednarek found his own net, again, and has now scored four own goals as a Southampton player in the Premier League; the joint-most of any player for the club in the competition, along with Jos Hooiveld.
