Real Madrid coach Carlo Ancelotti has spoken of working for Chelsea owner Roman Abramovich.
Ancelotti admits he feels more comfortable working for owners who have been life-long club supporters.
"The advantage of (AC Milan owner Silvio) Berlusconi or (Real president) Florentino Perez, is that they were supporters since they were children," said Ancelotti.
"Others, such as Roman Abramovich at Chelsea and Nasser Al-Khelaifi of PSG, they've been supporters only since they bought the club."
Ancelotti won the Premier League title with Chelsea, but lasted only two years under Abramovich.
