Anderson's been progressively getting better the last few seasons, and injuries have cocked it up. But it's only this season that he's looked good almost without exception, and that he's looked a force even as the game was nearing the end.
We rarely see him launch a 60 yard ball going no-where anymore, his passing is more measured and he is clearly becoming more and more refined in his decision-making. In addition he's been getting better at the goal-scoring bit, and he's given us a few memorable moments playing people through, like Rooney v Soton, Hernandez v whoever (escapes my mind at the mo), etc.
RvP had a hard time with injuries and didn't look world class until a couple of years ago. And it's harder still for a bloody centre mid to learn his trade. I'm happy to keep waiting for niggling injuries to subside, and for Anderson to step up proper... But for now he's making enough progress to justify my faith in his abilities.
I reckon talents like Ronaldo, Messi, Fabregas, Rooney etc. have skewed a lot of people's opinions. They think you ought to look the business before your 20s, never mind your mid-to-late 20s.
