Loved by some, hated by others.
The thought of a certain Jose Mourinho re-appearing in Chelsea's dugout would spark mixed reactions from the Blues' faithful.
The self-proclaimed 'Special One' has moved from West London and is currently managing Italian Champions, Inter Milan.
Mourinho created history with the Blues winning the Premier League in his first season at the club ending a league title drought which had stretched over five decades; the Portuguese mastermind then repeated the feat, the following season and became a legendary figure at Stamford Bridge.
After a poor start to his third season in England, Roman Abrahimovich lost his patience and before you knew it, Mourinho was history.
But Mourinho's departure meant Chelsea endured another three years without a Premier League title and watched Manchester United enjoy a hat-trick of titles.
Avram Grant and Luiz Felipe Scolari failed to bring any silverware to the club and even though Guus Hiddink's remarkable cameo at the club meant Chelsea won the FA Cup, the Premier League trophy continued to evade them.
A certain Carlo Ancelotti walks in, twice winner of the UEFA Champions League with AC Milan, and Chelsea's chances of returning to the path to glory may have been given a major boost.
A two year ban on transferring players for illegal dealing of French starlet Gael Kakuta might not be as big a problem as it appears to be.
Chelsea currently have a well-rounded squad led by the passionate John Terry (pictured above), which boasts the likes of Frank Lampard, Nicolas Anelka, Deco, Michael Ballack, Didier Drogba, Petr Cech and Ricardo Carvalho.
The Blues also have some young blood within their ranks, Franco Di Santo is currently on loan at Blackburn like Scott Sinclair and Micheal Mancienne; whilst new signing Daniel Sturridge along with the likes of Salomon Kalou, Fabio Borini, Jeffery Bruma, Sam Hutchinson, Micheal Woods, Gael Kakuta, Ryan Bertrand, and Jacopo Sala could provide a steady future for the club.
Chelsea, out of the big four, have got their Premier League title chase off to the best possible start and, besides Manchester City, are the only team to have won all of their games.
Florent Malouda's late winner against Stoke City wasn't the first time, the Blues have ground out three points at the end of a game and it certainly won't be the last time that happens.
However with Michael Essien, John Obi Mikel, Salomon Kalou, and Didier Drogba likely to be unavailable when the African Cup of Nations commences and the odd hiccups likely to occur, Chelsea will looking to gain as many points at they possibly can.
Nicolas Anelka's second half strike against Porto meant their European ambitions are also track, despite Drogba's absence.
The Blues are flying high and they are looking good.
Are they flattering to deceive?
Can Ancelotti's arrival stop Manchester United from making it to four consecutive titles?
