Alan Shearer has hailed Chelsea's start to the campaign after he tipped them to win the Premier League this season.
The Blues haven't ruled the top flight since 2017 under Antonio Conte, but are many people's favourites to topple Manchester City this term.
Shearer is amongst those and their impressive start suggests they will be right in the hunt.
Chelsea put in a professional display to see off Tottenham 3-0 on Sunday, their fourth win from five games.
The Blues withstood early pressure from the north Londoners before Thomas Tuchel made some half-time changes, thus allowing them to take control.
Chelsea's strength in depth is a huge plus and the signing of Romelu Lukaku looks to be the missing piece of the jigsaw.
Shearer told the BBC : "The Premier League title race is only just getting started, but Chelsea already look like they will be very hard to stop.
"Thomas Tuchel's side look seriously impressive right now, but they have done since he took charge in January.
"Even when they are not playing well or things go wrong - like it did when Reece James was sent off at Anfield last month - Chelsea still give very little away.
"As they showed in their brilliant 3-0 win at Tottenham on Sunday, the Blues have an extremely strong squad and a very good manager too."
The champions are next up for Chelsea.
Pep Guardiola's side will head to Stamford Bridge looking to snap a three-game losing streak against Tuchel's outfit.
The Blues saw off City in the FA Cup semi-final, the league and most notably in the Champions League final.
Their 3-4-3 system seems to pose plenty of problems for the Manchester outfit, who have been hit and miss this term, and Shearer expects them to give as good as they get next weekend.

"Chelsea's next test is against Manchester City at Stamford Bridge on Saturday, but that won't faze them," he added.
"They beat City three times under Tuchel last season, including in the Champions League final. He will be ready for Pep Guardiola again, I'm sure."
Tuchel confessed he wasn't happy with his team's first-half showing at the Tottenham Hotspur Stadium.
N'Golo Kante's arrival from the bench was a major game changer after the German had made his feelings clear at the interval.
"I was absolutely not happy with the first 45 minutes,' the German said on Sky Sports.
"In general we lacked intent, we lacked energy and needed to be more relentless in duels and to decide 50-50 balls for us.
"I had the feeling we wanted to impress by pure skills, but a game like this in the Premier League, a derby at Tottenham, it is not only about skilful play.
"It is also about aggression, about winning duels and performing better as a team. We lacked energy and spoke clearly about it at half-time"
