Chelsea may be Champions League winners and top of the Premier League but bookmakers remain unconvinced by their title credentials.
Their second-half dismantling of Tottenham on Sunday made it four wins and a draw from the opening five fixtures for Thomas Tuchel's men, with just one goal conceded.
Their 13 goals scored gives them an identical record to Liverpool who sit level with them on 13 points but still the spectre of Manchester City looms over the two early pacesetters - at least when it comes to the title odds.
City, who started the season odds-on, have drifted to 15/8 from 5/4 after drawing a blank against Southampton at the weekend.
The 0-0 draw leaves the reigning champions three points off the pace heading into Saturday's mouthwatering fixture at Stamford Bridge.
In fact, despite Manchester United (13pts) and Brighton (12pts) also sitting between Manchester City and top spot, it is Pep Guardiola's men who remain the market leaders, with the Blues priced up at 2/1.
And Planet Sport Bet spokesperson Scott Allen said much of the caution stemmed from the manner in which Manchester City strolled to the title last season.
"Chelsea have been rejuvenated under Thomas Tuchel and Liverpool have the air of the 2018/19 title winners about them again," said Allen.
"However, for all City's failed pursuit of Harry Kane and lack of an out-and-out goalscorer, we can't forget the way they racked up 15 wins on the bounce on the way to the 2019/20 title.
"They started that campaign unconvincingly, too."
Liverpool, who like City came out on the right side of VAR at the weekend, are 7/2, with Manchester United 5s.
Brighton remain 250/1 chances.
At the other end of the table, Norwich City's 15th successive Premier League defeat has hardened them in the relegation betting and they are now 2/5 from 4/7 to make another instant return to the Championship.
In their previous relegation campaign, Norwich had already accumulated six points from their first five games.
Their poor start hasn't translated into the First Manager to Leave betting, however, with Daniel Farke still an 8/1 shot.
