Arsenal spiced up an already intriguing Premier League title race as they beat lacklustre leaders Liverpool 3-1 to slice the gap to two points.
Arsenal deserved the points although they would not have expected a helping hand from an awful defensive mix-up between Virgil van Dijk and Alisson which allowed Gabriel Martinelli to restore their lead in the 67th minute.
Substitute Leandro Trossard then soothed any late nerves among the Emirates faithful as he secured the victory in stoppage time with a shot through Alisson's legs.
Bukayo Saka had given Arsenal an early lead with a cool finish in the 14th minute but a Gabriel own goal on the stroke of halftime undid all of their good work.
Heading for only their second league defeat of the season, Liverpool's frustrations boiled over as Ibrahima Konate was sent off in the closing minutes for a second booking after a foul on Kai Havertz.
Arsenal's win lifted them to second on 49 points to Liverpool's 51 with both clubs having played 23 games. Champions Manchester City, who play on Monday, have 46 from 21 games.
Manchester United climb above West Ham into sixth with 3-0 victory
Manchester United's Alejandro Garnacho netted twice after Rasmus Hojlund scored on his 21st birthday as the Old Trafford side beat West Ham United 3-0 to climb above the visitors into sixth place in the Premier League.
On the heels of a 4-3 win at Wolverhampton Wanderers on Thursday, Erik ten Hag's team now have 38 points after 23 games, eight adrift of fourth spot. The Hammers are seventh with 36.
Hojlund scored in the 23rd minute when Casemiro prodded the ball forward after West Ham failed to clear a high ball. The Dane knocked the ball past a couple of defenders before firing home from the centre of the box into the bottom corner.
Hojlund, who did not score his first league goal until Dec. 26, became the youngest player in the Old Trafford team's history to score in four consecutive Premier League appearances.
Garnacho doubled the lead in the 49th after his shot from the corner of the box took a big deflection to send substitute goalkeeper Lukasz Fabianski the wrong way.
The Argentine netted his second in the 84th after Kalvin Phillips lost the ball and Scott McTominay pounced, finding Garnacho in the box.
Wolves hammer Chelsea 4-2 with Cunha hat-trick
A hat-trick from Wolverhampton Wanderers' Matheus Cunha again exposed Chelsea's defensive frailties as the visitors came from behind to record a 4-2 win at Stamford Bridge.
Chelsea, who lost 4-1 at Liverpool in midweek, went ahead in the 20th minute through Cole Palmer. But two minutes later Joao Gomes found Brazilian compatriot Cunha whose shot took a big deflection off Chelsea defender Thiago Silva.
Wolves' second just before halftime hit Axel Disasi and was given as an own-goal with Chelsea goalkeeper Djordje Petrovic wrongfooted.
Cunha made it 3-1 midway through the second half, after Pedro Neto caught Chelsea on the break, and scored his third from the spot in the 82nd after being brought down by defender Malo Gusto.
Brazilian Silva scored a consolation header with four minutes of normal time remaining but by then many home supporters were already leaving the stadium.
