It's guesswork with him. You can see it. After he used up his 50/50, he kept going for the ask the audience. And after that it was all about giving Stoke everything he could.
After the early yellow which Van Persie bought us, I knew he'd be itching to even it up. Every 50/50's gone their way. That's the thing about appealing for fouls...you need to know when to play the right card. Instead of steaming in for the 3rd minute, Van Persie should've saved it for a pen shout.
