Real Madrid boss Zinedine Zidane insists he has no doubt Cristiano Ronaldo will win a fourth Ballon d'Or come January, but his hat-trick in a 3-0 defeat of Atletico Madrid may convince others. 

In the final La Liga derby at Atletico's Vicente Calderon, Ronaldo's deflected free-kick opened the scoring before he struck from the penalty spot and completed his 39th Real hat-trick with a simple finish from Gareth Bale's fine cross. " I never had any doubt.  It is not his three goals that are going to change my mind," said Zidane on Ronaldo's case to be crowned the world's best player for 2016. " He showed it all last season, he shows it in every game ... Three goals in a match like this may make everyone agree, but for me there is no debate." 

Victory extends Real's lead at the top of La Liga to four points from Barcelona, who missed the ill Lionel Messi in a 0-0 draw at home to nine- man Malaga. 

Borussia Dortmund stunned Bayern Munich 1-0 to leave RB Leipzig the shock German Bundesliga leaders.
