Previously yes, I think he's way past his best. Personally I think he's on the way down and I worry that he's got too much say in the dressing room.
Fact is, we were outbowled in English conditions by Pakistan and for me, he was the main culprit. It's too comfortable him, he can pretty much do what he wants without fear of being dropped - so personally I'd drop him. Freshen things up. Send a message to the whole squad that nobody is safe. Maybe then we'd see more fight and character. Instead of just going through the motions as we slip to ANOTHER annihilation.
