Manchester City issued a huge statement of intent in the race for the Premier League title with a 3-0 win at Chelsea on Sunday.

Pep Guardiola's team moved to within six points of leader Arsenal ahead of this weekend's top-of-the-table clash between the two teams. City also has a game in hand.

Nico O'Reilly, Marc Guehi and Jeremy Doku all scored in a blistering second-half performance at Stamford Bridge as City took full advantage of Arsenal's shock defeat to Bournemouth on Saturday.

"We know that we still have everything in our hands," Doku said.

At the other end of the table, Tottenham's survival fight took another blow after a 1-0 loss to Sunderland left it rooted in the relegation zone.

In coach Roberto De Zerbi's first game in charge, Spurs fell to their 16th league loss of the season. Its 14-game winless run in the league dates back to Jan 1.

Nordi Mukiele's deflected shot sealed the game at the Stadium of Light and plunged Tottenham's campaign deeper into crisis.

Tottenham is two points adrift of safety with six games to go. Its plight wasn't helped by fellow struggler Nottingham Forest drawing 1-1 with Aston Villa.

Crystal Palace came back from 1-0 down to beat Newcastle 2-1 at Selhurst Park.

Title charge gathers pace

While Arsenal's form has hit a slump at the worst possible time, City made it three statement wins in a row after rolling over Chelsea.

Victory followed City's triumph over Arsenal in the English League Cup final and a 4-0 rout of Liverpool in the FA Cup the previous week.

While those three results all came in different competitions, City's charge has an ominous feel about it after twice chasing down Arsenal's lead to win the title in 2023 and 2024.

Second-placed City has the chance to cut the gap at the top to just three points with a victory over Arsenal at the Etihad this Sunday. Guardiola called for respect for Arsenal when looking ahead to that title showdown.

"The respect I have for Arsenal, what they have done the last few years. I know the manager, the players, the quality, how they compete in every circumstance, that's the biggest job we have. There is a tactical issue, maybe we will adjust some things," Guardiola said.

"They have been the best team in this country, in Europe, so far. Beating Arsenal once is so difficult, imagine beating them twice within a few weeks," Guardiola said. "I would like to say to my fans — respect Arsenal a lot, they are an extraordinary team. Come to join us from minute one, because the players will do the maximum."

Rayan Cherki was the inspiration at Stamford Bridge — setting up goals for O'Reilly six minutes after halftime and Guehi in the 57th minute. Doku rounded off the win in the 68th.

The result didn't help Chelsea's bid to qualify for the Champions League, leaving it four points behind fifth-placed Liverpool.

Liam Rosenior's team has won just one of its last seven league games.

In those three league defeats, Chelsea has failed to score and Rosenior said his team had fallen well short of the standards he demands.

"Not good enough in the second half. It's a similar story for the past month now, in terms of dealing with setbacks," he said.

"If you go down against teams as good as this, what you have to do for the next five minutes is to stay in the game. It ended up being a really, really difficult second half."

Spurs' crisis deepens

The numbers just keep on getting worse for Tottenham.

Now on its third coach of the season, it is more than three months since its last league win and it has just one point from a possible 24. This was a seventh defeat in eight games.

If the hope was that De Zerbi would provide an immediate bounce in form after replacing Igor Tudor, it didn't come in what was a typically toothless display at Sunderland.

While the new coach could point to bad luck, given the nature of Mukiele's 61st-minute winner, which took a wicked deflection off Micky van de Ven, his team rarely looked like finding a way back into the match — even during 11 minutes of added time at the end.

An injury to Cristian Romero made a bad day worse for Spurs, which next face Brighton, one of De Zerbi's former clubs.

Forest moved three points clear of Spurs after a draw at the City Ground. Neco Williams' long-range shot leveled the game after a Murillo own goal gave Villa the lead.
