Spanish forward Pedro Rodriguez scored twice as red-hot leaders Chelsea crushed Bournemouth 3-0 on Monday to register a club-record 12th consecutive Premier League victory.
Pedro struck either side of Eden Hazard’s 50th English league goal at Stamford Bridge as Antonio Conte’s side opened up a provisional nine-point lead at the summit in the Boxing Day action.
Olivier Giroud prevented Arsenal losing more ground, his 86th-minute header snatching a 1-0 win over West Bromwich Albion to lift Arsene Wenger’s side above Manchester City into third place.
But with second-placed Liverpool not in action until Tuesday, when Stoke City visit Anfield, Manchester City can climb to second if they win at Hull City in the late game.
Zlatan Ibrahimovic scored one goal and set up two others as Manchester United closed to within three points of the Champions League places by beating Sunderland 3-1, while champions Leicester City lost again.
Chelsea chase Arsenal record
Chelsea’s victory over Bournemouth left them one win short of Arsenal’s 2002 record of 13 successive victories within the same top-flight season.
With Diego Costa and N’Golo Kante suspended, Conte paired Cesc Fabregas and Nemanja Matic in midfield, with Hazard starting up front, flanked by Willian and Pedro.
Pedro broke the deadlock in the 24th minute, curling a left-foot shot into the top corner from Fabregas’s pass following a neatly worked corner.
Hazard made it 2-0 four minutes into the second half, rolling a penalty into the bottom-right corner after he had drawn a foul from Simon Francis, with Pedro adding a deflected shot in stoppage time.
Beaten 2-1 by Everton and then City on their two previous outings, Arsenal narrowly avoided going three league games without winning for the first time since January 2012.
Alexis Sanchez’s shot against the post looked to be the closest Arsenal would come until Giroud marked his return to the starting XI by looping a header over Ben Foster with four minutes to play.
Manchester United enjoyed a far less complicated afternoon, sinking Sunderland to record a fourth successive league win for the first time under manager Jose Mourinho.
Daley Blind opened the scoring in the 39th minute, striding onto Ibrahimovic’s lay-off and steering a shot into the bottom-right corner.
Ibrahimovic got on the scoresheet nine minutes from time, slotting past Jordan Pickford to chalk up his 17th goal of the season, before Henrikh Mkhitaryan sealed victory with a clever back-heel.
United drew level on points with fifth-place Tottenham Hotspur, who visit Southampton on Wednesday.
Fabio Borini replied for the visitors, but it was a return to forget for Sunderland manager David Moyes, sacked by United in April 2004.
Champions Leicester’s woes continued as they were condemned to a ninth defeat of the campaign by Everton, who won 2-0 at the King Power Stadium courtesy of Kevin Mirallas and Romelu Lukaku.
Leicester, who were without the suspended Jamie Vardy, have won just one of their last nine league games and sit three points above the relegation zone in 16th place.
West Ham United eased their relegation fears by winning 4-1 at second-bottom Swansea City through goals from Andre Ayew, Winston Reid, Michail Antonio and Andy Carroll.
Andre Gray’s late effort gave Burnley a 1-0 win over Middlesbrough, the striker’s shot squirming beneath visiting goalkeeper Victor Valdes.
