Carlo Ancelotti believes Real Madrid and Barcelona can reach the Champions League final.

The Italian coach also does not see much difference between the two Spanish clubs despite Barcelona's 15 point lead in LaLiga.

"Clearly Champions League games are decided by the smallest of details and in a one off game it is sufficient for a refereeing decision to knock someone out," the former Real boss said.

"Madrid and Barcelona are favourites for their experience and because they have Ronaldo and Messi.

"It is clear (Juventus and Roma) are not favourites becasuse they are up against two European powers but they still will have their chances."
