Everton were the only Premier League team that failed to score on what was a thrilling weekend in English football’s top-flight.

Ronald Koeman’s side were battered 5-0 by a sensational Chelsea on Saturday night, who in turn overtook Pep Guardiola’s Manchester City at the top of the league after their 1-1 draw at home to Middlesbrough earlier in the day.

However, they were soon displaced by Jurgen Klopp’s (Pictured) Liverpool, who thumped Watford 6-1 at Anfield on Sunday afternoon.

Sunday’s North London derby at the Emirates ended 1-1 as Harry Kane’s penalty cancelled out Kevin Wimmer’s own goal to preserve Tottenham’s unbeaten start to the league season, while Jose Mourinho’s Manchester United ended a run of four league games without a win courtesy of a 3-1 success at a lacklustre Swansea.

There were much-needed wins at the bottom for Sunderland, Hull, and West Brom, who overcame Bournemouth, Southampton, and Leicester respectively by the same 2-1 scoreline, while Burnley made it seven points from nine after beating Crystal Palace 3-2 at Turf Moor.

West Ham and Stoke shared the spoils at the London Stadium in the other match of the weekend, and there was a lot to be learned from an exciting weekend in England’s top tier.

Thus, here are FIVE things we learned from this weekend’s action…

Three at the back could be the way to go

Chelsea’s sensational recent run has come about since changing to a back three, and they made it five wins on the bounce with a 5-0 thrashing of Everton.

In what many have regarded as one of the best displays the Premier League have ever seen, the Blues ran riot over what was, prior to kick-off, the second-best defence in the league.

However, it wasn’t just Chelsea boss Antonio Conte who utilised the back three to great effect this weekend, so did Tottenham manager Mauricio Pochettino.

The Spurs boss played Eric Dier, Jan Vertonghen, and Kevin Wimmer as part of a back three and, although they are not as accustomed to playing it as the Chelsea defence, they did well and helped Tottenham to a deserved point against North London rivals Arsenal.

It could be a system Pochettino employs more readily and, based on Conte’s success as well as its use from Pep Guardiola and Slaven Bilic, it could be the way to go this season.

Eden Hazard is back

We knew that Eden Hazard wasn’t going to endure another poor Premier League season, but Saturday’s display against Everton suggests that not only is he back, he may even be better than before.

The Belgium international was sensational throughout the game on Saturday, netting two superb goals, but also repeatedly causing the Toffees defence problems with his pace, tricky, and all-round brilliance.

Him and Diego Costa appear to have got their mojo back this season, and it’s a frightening combination for any side in the Premier League to have to deal with.

Burnley have improved from their last PL campaign

It’s now two wins and a draw in their last three matches for Sean Dyche’s Burnley, who look stronger and with a genuine chance of survival this time around as opposed to their ill-fated spell in 2014/15.

The Clarets showed their dogged and resilient side in drawing with Manchester United last week, and then showed a different side by beating Crystal Palace 3-2 on Saturday.

By being patient and once again solid in defence, Dyche’s men hit Palace on the break with devastating effect, with Ashley Barnes’ winner coming courtesy of just that tactic.

They look a rejuvenated side this season, are up to ninth in the league table, and look better equipped than ever to stay in the top-flight.

Sunderland have given themselves a chance

Arguably the biggest result of the weekend was Sunderland’s 2-1 success away at Bournemouth, their first league win of the campaign.

At 1-0 down after 11 minutes, you’d be forgiven for thinking that the Black Cats might have a different manager in place for their game against Hull after the international break, but David Moyes’ side showed the spirit and character unseen from them in the early stages of the season to get back into the match.

Victor Anichebe was excellent throughout and got the equaliser, and then the ever-reliable Jermain Defoe slotted home a second half penalty to secure the win.

However, it was a much better team effort from Sunderland, with Jordan Pickford outstanding in goal and Duncan Watmore full of running, and it gives them a foundation to build on going forward.

Although they are still bottom, they have given themselves a chance of avoiding the drop.

Swansea are seriously struggling

Victories for Hull, West Brom, and Sunderland gave those sides near the bottom of the Premier League some respite after a tricky start, but the same cannot be said of struggling Swansea.

Bob Bradley replaced the sacked Francesco Guidolin last month, but he is still searching for his first win in charge at the Liberty Stadium after a disappointing 3-1 defeat at home to Manchester United.

And it was the manner of the display which drew boos from large sections of the home crowd after the game, with the defence awful and the attacking unit blunt throughout the match. In fact, it took them until the hour mark to touch the ball in the United box.

Much has been made of Sunderland’s woeful start to the season, but they are now level on points with the Swans at the bottom.

This could be a very long season for Bradley and co.
