Gus Poyet: "I can assure you [Cattermole and Dossena] know what they've done. That's very important.
"They know there is a limit, and they need to be careful. I hope it never happens again, but we'll see.
"We all make mistakes, and there is no explanation why you do it. It happens in a split second. But if you do it every week, you've got a problem.
"When someone does something really, really stupid and it's repetitive, he doesn't have a chance with me.
"They need to be professional."
