...because they probably already knew he was possibly going to be sold.Just because Carrick, Fletcher, Giggs, Berbatov and Hernandez haven't played yet doesn't mean they will forever be behind Cleverley and Welbeck. They might be, but we don't know that yet. You can't decide the established order of a club this early in the season, especially before the end of the transfer window. Only after the next few game weeks will we really know exactly what Mereiles will do at Chelsea, just as we'll find out whether Cleverley is really going to be our first choice central midfielder.
There is the established order at United that Rooney starts, but I wouldn't say there is an established order beyond that. It all comes down to form and rotation. If you can't rotate a very large squad (keep in mind we also have Owen, Macheda and Diouf who will likely start cup games), you end up in a bad position with your strikers.
To say Tevez is behind Aguero and Dzeko because of their start to the season is also a little hasty. He's a massive player for City, leaving or not, and when they pay him that much and were not wanting him to go (they would have sold him cut price if they really wanted him to leave). He'll play a lot of games this season and he'll start a large number of them, too.
Your Arsenal heirarchy is very accurate, though.
Drogba and Torres are the primary duo at Chelsea. Drogba will ease off though, purely due to his age - but I can tell you that when he played against us late last season, he was easily the most dangerous man on the pitch for Chelsea... his brute strength allows him to brush past any central defender when he's got the ball at the right spot, so writing him off is something I'll never do... I just can't see him ever really being a bad player, just a tired one.
Torres will become more prominent. But does that mean that Torres is past it? No. He's just not returned to his best form, he's not reaching his potential - yet. But he will. A player of Torres' quality does not subside from "best striker in the world" to "not the same player he used to be" at the age of 27. He is that player, he's just lacking in confidence. He'll get it back when he scores a few goals, and he'll likely piss us all off when he scores against our clubs. He's too good to not return to the guy who could score a hattrick against any top club in the world. The guy is a massive talent.
Lukaku is untested in PL but if he is as good as he is made out to be, Drogba will be replaced by Drogba, Part II. If Chelsea manage another 15 years of Drogba, well, smurf me, that's going to be difficult for all of us.Sturridge I think will be sold eventually, but he was the best attacking player for Bolton last season so he's capable of shining at PL level already. He's quality for a #3 or #4 striker.
I don't know what you're getting at regarding Chelsea's midfield. They have Essien and Obi Mikel who are both defensive midfielders. They don't need another. And they simply don't have trouble in that area. I've never seen a Chelsea game where they have struggled in the DM region. Their defenders are that high quality that they don't really have to worry about it. I mean, we have no DM's at United, and we won the title last season with that setup. Chelsea doesn't lack defence, Chelsea lacks creativity. Lampard was effective but has not been creative for some time.
Malouda was very much out of favour on occasions last season and Ramires is crap. Ramires was not played as a DM, he was played as a wide right midfielder. And I have never seen Kalou playing as a DM - he is a wing/forward. He's always been one. Did they really play him as a DM? And Obi Mikel and Essien are DMs. Essien is, when fit and in form, arguably the best DM in the world. I would love it if we had signed Essien instead of Chelsea. Obi Mikel is a DM, too, because he isn't good going forward. He's like a poor man's Fletcher - not good enough going forward so he plays in the DM position instead. Only, Obi Mikel isn't amazing there, either.Fletcher has more commitment and drive than Obi Mikel, which is why Fletcher is regarded higher.
EDIT: And I just checked and Meireles won 2010-11 PFA Fans' Player of the Year. Malouda and Lampard most certainly did not. How he would have won that award without being highly regarded by Liverpool fans is beyond me.
