Liverpool boss Roy Hodgson is convinced Chelsea are due a bad run of form.
The Reds host Chelsea tomorrow at Anfield.
Hodgson, who got to know Ancelotti during his time at Internazionale, when the Italian was working with the national team under Arrigo Sacchi, said: "At the moment they are there because they have made a good start, but I'm sure Ancelotti would also tell you - being an experienced manager who has worked in Italy - that you can have a spell which goes the other way.
"It may not be long before they have a bad spell and you're asking what's gone wrong with Chelsea. If, after 38 games, you ask me what is it that made Chelsea champions, I might be more interested in answering the question, but not after 10."
