Drogba was on fire last season, he was scoring for fun at times. Imo the problem wasn't so much that you were missing a scoring threat, it was more that you were missing an established partnership. Schevchenko was in his first season, hadn't played with Drogba or in the Premiership before, on top of that he doesn't quite have the legs he used to, so it's no suprise to me that he didn't set the Premeirship on fire. He'll do better this season, no doubt, it's moer a queastion of will better be good enough. Kalou just imo isn't good enough, he'll have moments of greatness but like you said, he's so inconsistent
Personally, I don't think Drogba should have won player of the year, your bound to say he does, I'm bound to say he doesn't and that Ronaldo does. But I base my view on the fact that Ronaldo did a hell of a lot more than just scoring goals last season, Ronaldo was phenominal last season, not to take anything away from Drogba, he was on fire too, but for me even looking at it as neutrally as I can, I still see Ronaldo as the winner last year. Both Chelsea and Man U suffered big set backs with injuries and we've both strenthened out squads well. Next season should be interesting, especially with Tottenham creeping up and Liverpool making a few good signings too.
