With last season's top three sides all starting the new campaign with different managers, do the west London club hold an advantage over their title rivals?POLL
After a long time coming, it has finally been confirmed. Jose Mourinho has returned for a second stint at Chelsea.
The 50-year-old insists he is looking to stay at Stamford Bridge for the long term and has already targeted "a couple" of new signings during the summer transfer window.
So, with Mourinho back at the helm at Chelsea, where does this place the club in terms of challengers for the Premier League title next season?
David Moyes will be looking to follow in the title-winning footsteps of Sir Alex Ferguson at Manchester United next term, while Manuel Pellegrini, who is set to be named as Manchester City's next manager, will also want to make an instant impact at the Etihad Stadium.
What do you think? Are Chelsea favourites to win the Premier League next season? Or is there still too great a gap between the Blues and the Manchester clubs for even the Special One to conquer? Who would be your pick to secure the title?
