Not sure when retaliatory, reckless challenges were ever interpreted as not being reds. Messi is going in with full intent of fouling Ramos along the way to getting the ball. Gets absolutely nowhere near it, because Ramos tucks it back and trips him with both legs. I suppose we let it slide only in special cases of certain people on the receiving end who have a reputation of being a professional ass
But again, who cares. It's just a bit of an anecdote.
He didn't went there to hit Ramos badly. He goes for the ball and knows there is a big risk he'll hit Ramos. That's different. He hits Ramos with the 2nd leg after he misses the ball with the first leg. The first leg doesn't even land on Ramos' leg. It lands where the ball was like a fraction of a second earlier. He puts the leg next to Ramos and he slides a bit, and then hits Ramos with the 2nd leg, hence the yellow.
Sure, it's reckless challenge. Not every reckless challenge is a red card. Bale had like 2 fouls like this one. One on Semedo and one on Iniesta.
It's very similar to Bale's yellow card foul in the 2nd half actually.
And this is Ramos vs Suarez in the Bernabeu game. Roberto's a red, but this is a yellow. Right...
Speaking about Madrid players being fair play
I have some on Marcelo too. Filled Messi with blood in the 3-2 game. After an elbow to the face. Stomped on Pedro's leg in the CL clasico. Kicked Messi in the Supercup game, then scissor kicked Fabregas too.
Madrid players are the last players in the world who should be seen as being fair play.
