Manchester United also picked up 10 points from their opening seven league games under David Moyes in 2013-14 but they had a worse goal difference that season
Manchester United "have big decisions" to make about the future of manager Jose Mourinho, according to former defender Rio Ferdinand.
The Red Devils' 3-1 defeat at West Ham on Saturday made this their worst start to a top-flight season since 1989-90.
It is their third loss in seven league games and follows a home Carabao Cup exit to Championship side Derby.
"There will be conversations at the top level about the future of the manager and the squad," Ferdinand told BT.
"The basics are not being done and something has to be said.
"You can't let a situation like this continue throughout the season - wars in the press, leaks, players on one side of the dressing room, Mourinho and his staff on the other. If that continues this will be one of the worst seasons in the club's history."
'A war within the club' - Scholes
West Ham's victory at London Stadium was their biggest over Manchester United in 36 years, achieved through Felipe Anderson's fifth-minute strike, a Victor Lindelof own goal and a simple finish from Marko Arnautovic after questionable defending.
Substitute Marcus Rashford had given the visitors hope when his smart finish from a corner reduced the arrears to 2-1, but former midfielder Paul Scholes said "the fight was just not there".
"That was as bad as you've seen from a United team for a long time," Scholes told BT Sport. "The attitude has been questioned before and it has to be questioned again. The hunger and desire to get amongst people wasn't there.
"At this minute, this club is in a bit of a mess.
"Is this the end for the manager? I don't know. Who's going to get more out of this team? We just know at this moment in time it feels wrong."
Analysis - 'Sacking Mourinho would fly in face of Glazer ownership'
BBC Sport's Simon Stone
No sooner had the final whistle gone at London Stadium than the bookmakers were sending round the inevitable press releases stating Mourinho was the favourite to be the next manager to leave his job.
The reality is if that scenario unfolds, it would fly in the face of the Glazer family's ownership of Manchester United.
While the reclusive American family, who never talk to the media about United, can be accused of many things, being knee-jerk is not one of them.
In the immediate aftermath of their takeover in 2005, Sir Alex Ferguson was in the process of trying to rebuild his team, which had fallen well behind Chelsea and Arsenal. The Glazers stuck with him.
David Moyes' tenure was not brought to an end until United knew it was mathematically impossible to qualify for the Champions League, despite numerous awful results and even a plane flying over Old Trafford trailing a banner that demanded his exit.
When rumours circulated around Christmas 2015 that Louis van Gaal was about to be sacked, they proved to be false. It was only at the end of the season when, once again, United had not finished in the top four, that he was removed.
I was told earlier this week results would be the criteria Mourinho would be judged by. As bad as the defeat at West Ham was, I didn't get the impression we were talking about one.
