Carlo Ancelotti has suggested Chelsea's current form is as mystifying as AC Milan's infamous defeat in the 2005 Champions League final against Liverpool.
The Italian saw his side go 3-0 up in the first half against the Reds in Istanbul, only to see his side capitulate and lose the game on penalties after a comeback from Rafael Benitez's side.
Speaking exclusively to the Daily Mail, Ancelotti compared Chelsea's current form to the outcome of that 2005 final.

He said: "Sometimes you can’t explain why things happen – what is going wrong. It is a mystery. How did we lose (with AC Milan) in Istanbul when we were three goals up against Liverpool at half-time?"
The champions' current form is just as he says: completely mystifying. Chelsea have won just three of their 12 Premier League games this season and are showing only limited signs of recovery.
The international break may have come at a good time for the Blues, giving Jose Mourinho some time to tweak his tactics before the season resumes.
Ancelotti managed Chelsea himself for two years between 2009 and 2011, during which time he won the domestic double, and suggested that motivation may be one of the reasons for the club's poor form this season.
"I look from a distance at Chelsea and I think they won the title easily last year and I don't think they are so motivated this year."
FOOT OFF THE GAS
Widely regarded as one of the greatest managers of his generation, Ancelotti has guided three different clubs in three different countries to league titles, while winning the Champions League with two of them.
He's currently taking a break away from football after leaving Real Madrid in May 2015, but hasn't ruled out a return to Stamford Bridge should Mourinho face the sack. The Italian was confident, though, that the Portuguese's job is safe.
"I would have no problem with Chelsea, but Jose won't be sacked. They already choose to keep him, and I think they made a good choice."
He also had some warm words for his managerial counterpart and the Chelsea fans, backing the club's most successful manager to turn this season around.
"Mourinho is one of the best managers in the world, no doubt. I look at his body language and he's OK.
"He is not so worried. He has confidence. During the Dynamo Kiev game, the supporters were singing his name. He'll sort it out."
November will prove a key month for Chelsea as they play a number of important games, hosting Norwich City at Stamford Bridge week Saturday, before playing a vital match away to Maccabi Tel-Aviv and ending the month with a London derby against Tottenham Hotspur.
Good performances in all of these fixtures would certainly boost Mourinho's season, especially heading into the frantic Christmas period, which is arguably the most important time of the domestic season.
