You obviously don't read properly my friend. I spoke about Clichy's game by game improvement and then I gave you a recent example to back up the opinion that he has improved as the season has carried on.
I also said before that how he has stopped the best wide midfielders in the league and when the champs league resumes we will see how he handles it on a wider scale. He has stopped Lennon, Ronaldo, Giggs, Rooney, Gerrard and Pennant in the prem over the course of the last 4-5 months. Bentley who has been terrorising defences got no luck, Ashley Young ditto. Sowed up SWP at Chelsea when he came on too (though that isn't particularly difficult given his recent form).
Given that he has consistently performed and has shown consistent improvement, he is doing all that is asked of him. I am giving you my opinion as I watch every single game; on the other hand, as you say you are in england, I imagine you watch perhaps 1/5 of them in their entirety but correct me if I am wrong.
You talk of development growth stage is pointless because I am talking about one specific player; it doesn't matter what happened to other players, your continued reference to it is a logical fallacy, a non-sequitir perhaps.
Clichy played well against Liverpool (I am assuming you mean the FA cup game, but perhaps you confused him for Traore in the carling cup game).
But then again, if you think Henry has been sublime since returning for us, perhaps you just aren't a good judge of player performance. He has scored 4 in 4 and has been one of the worst players on the pitch in all four games.
