Indeed, Jose Mourinho's Blues - galvanised by a brace of specialist players acquired in the summer; Diego Costa and Francesc Fabregas - are already atop of the Premier League table, have scored 19 goals and returned 16 points from five wins and one draw in six matches.
Costa's prolific ability in front of goal and the creative ingenuity of Cesc in midfield have been key to Chelsea's early season dominance - and while Arsenal pose a threat when the two collide at Stamford Bridge on Sunday, should the West Londoners emerge unscathed then it could set them up for a glorious unbeaten Invincible-style season.
That is, according to Keown, who said: "Costa is on fire, Fabregas is playing well, the players are all embracing the change under Mourinho, he seems to make everyone better but Arsenal are putting a team together and the performances are improving, so you can’t discount Arsenal and Mourinho will know that.
"I think if Chelsea win it they will start to feel they can win the league, and even go unbeaten," commented Keown, himself a three-time Premier League champion.
"They’ve already been to Manchester City and done well in getting a draw, and all they need to do is start ticking off all the big contenders.
"Chelsea have a really special group this season and if they beat Arsenal I’m sure they will start to feel they can win the league."
