I don't know about comparing the development of the players, as such, but the debate over Alexis certainly reminds me of the one(s) people had over Rooney. On the one hand, he gets too much stick for performances that are, strictly speaking, decent enough. But on the other hand, the discrepancy between his name/status and his actual quality is huge.
He's miles away from what used to be his level, just like Rooney was. And that will - of course - influence people's opinion on him. It's very difficult to assess the performance of a supposed top player (on huge wages) as though he were another honest squad grunt "putting in a shift" (that the individual shift may indeed be decent/adequate simply isn't what you consider first and foremost - you look at the bigger picture, and rightly so - I suppose).
