By your logic, Sergio Ramos is rubbish aswell cause he gets a ton of red cards.
How many times should Herrera, etc be sent off? What about Ibra on Dawson? You could go on all day. Fact is, he wasn't sent off. And those challenges weren't in the box so its not like he risked a penalty or anything. I'm glad he got "stuck in" and let them know he was there. We've been lacking that since Keane.
Swear some people made their minds up about him and now don't want to admit they were wrong so they're clutching for straws on this.
