Chelsea have taken only five points from their opening six Premier League games this season – their worst start to a campaign since 1978.

Sunday’s 1-0 loss to Aston Villa leaves them in 14th and extended their winless run to three games.

Here the PA news agency looks at the reasons behind the west London club’s performance problems.

Is Mauricio Pochettino the right man?

Pochettino’s youthful Chelsea squad have experienced teething problems, with their only league win coming with a 3-0 victory over newly-promoted Luton. Their forwards have been wasteful in front of goal, with striker Nicolas Jackson missing seven big chances in six games with just a single goal to show for it. The Blues have shown signs of promise at times but individual errors and questionable changes to the formation will mount pressure on Pochettino, who is expected to perform after Chelsea’s £1 billion-plus transfer spree since May 2022.

How does Pochettino compare to other Chelsea managers?

Pochettino has struggled to improve a Chelsea slump that started under Graham Potter and continued during Frank Lampard’s woeful temporary return. In Pochettino’s first six Premier League games the Blues have scored only five goals, winning once and losing three times. That is slightly better than Lampard’s second spell at the helm, which saw the Blues score seven goals and take four points in their first six games before finishing 12th. Potter managed nine goals and 11 points in his first six games, while Thomas Tuchel – who won three trophies during his Stamford Bridge tenure – picked up 14 points in his first half a dozen Premier League fixtures. With a lack of goals holding Pochettino’s side back, the 51-year-old will hope that an increase in chances taken can turn the tide.

What about all the money they spent?

Todd Boehly’s Clearlake Capital consortium forked out over £450 million on transfers this summer and have broken the British transfer record twice since January to land midfielders Enzo Fernandez and Moises Caicedo. Caicedo has had a mixed start at Stamford Bridge after his £115 million move from Brighton. The Ecuador midfielder had a poor cameo on his debut against West Ham before he gave the ball away for Anthony Elanga’s second-half winner against Forest. Jackson is yet to live to up to his exciting first two games in blue and has missed golden chances which have cost Pochettino’s side. Fernandez, however, is the shining light in Chelsea’s midfield and has shown his quality on the ball.

Are injuries to blame?

Chelsea had 12 players missing through injury for last week’s 0-0 draw at Bournemouth, forcing Pochettino to rotate once again. Christopher Nkunku and Romeo Lavia are yet to make their debuts for the club due to being sidelined and the exciting Carney Chukwuemeka’s knee injury at West Ham was more serious than what was first hoped. Suspensions picked up by Nicolas Jackson and Malo Gusto will add further problems for Pochettino when they face Fulham.

What’s next for Chelsea?

After hosting Brighton in the Carabao Cup and a west London derby at Craven Cottage, the Blues face a tough run that includes Arsenal, Tottenham, Manchester City, Manchester United and Newcastle in their next eight league games. They will need to find an upturn in form if they do no not want to slip further out of the race for European qualification for a second successive season.
