It took just three minutes for a divisive referee decision in Sunday's Clasico as Cristiano Ronaldo went down in the penalty area under a Samuel Umtiti challenge.
The Real Madrid No.7 appeared to be on the receiving end of contact from the Barcelona defender three minutes in - but was it enough contact to justify giving a penalty?
The officials at the Santiago Bernabeu decided against it - and thousands of football fans made their varied opinions crystal clear on Twitter in the moments afterwards.
Ronaldo shouldn't just fall down that easily, he could have still reached the ball and scored

Would love to see pique tweet about that blatant penalty on Ronaldo

Not even 2 minutes and Ronaldo is already looking for a penalty.

That's a pen on Ronaldo but ref decides not to make a big decision early

Ronaldo is an elite athlete of the highest order. A tap on his leg like that is not enough to bring him to the ground.

That should have been a penalty for Ronaldo.

Victory in the Spanish capital would revive Barca's Liga hopes, while defeat would see them six points adrift of their Clasico rivals and triumph surely no longer within their grasp.
