It's like he doesn't want to step up his game.
He's had a collarbone injury
but he's not done enough since he came back. At the end of last year he was untouchable but he made a slow start to the season and just can't seem to live with the rookie Marquez.
This may be the best chance he ever has of winning the title and it looks like it is slipping away now.
He's finished second in the championship three times already, third on another two occasions, and he may end the season with another runner-up spot.
This is his eighth season in MotoGP and although he's only 27 and will have plenty of years left, you wonder if he's destined never to win the title now.
British GP: Jorge Lorenzo pips Marc Marquez at Silverstone
You won't be able to get into the paddock. I have no idea where everybody gets their passes from for the two Italian rounds at Mugello and Misano - you can't move all weekend, it will be full-on 'Rossimania'.
He was a huge talent and we can only imagine how good he would be now. The racing will no doubt be excellent this weekend but if we had been lucky enough to see Simoncelli dicing with Marquez, Pedrosa, Lorenzo, Rossi and Cal Crutchlow then it could only have been better...
