Atletico Madrid blew their city rivals away and also blew the title race wide open.
Tiago Mendes opened the scoring.Saul Niguez doubled the lead with a super scissor kicked second goal.Antoine Griezmann and Mario Mandzukic scored 3 and 4 in the second half.
This is surely the best that Atlético have played since Simeone took over as coach.For a team that had been unable to beat Real Madrid in 14 years and 25 games the transformation that he has wrought is remarkable.
Atlético are now unbeaten in six derbies this season, winning four of them and winning this one so comprehensively that Real Madrid seemed spectators for most of the second half.
Altetico are now four points behind Real.
“We’re still top, but we can’t lose 4-0 to anyone,” Cristiano Ronaldo said in disbelief at the end.
