I'm a qualified - albeit no longer active - referee. My 2p
The Ref was poor - very poor.
1/ The Malouda free kick / penalty - that was bottled. First contact outside the box, but the foul that he finally gave was inside. That would have taken a strong decision to give it though, and giving the freekick outside was probably judicious application of Law 18.
2/ Drogba and the shirt pull. Clear penalty, since according to the laws holding or pulling is a foul and according to the IBD (international board decision) is also a mandatory caution. Again, harsh but they are the laws. Unfortunately Drogba's theatricals don't accentuate the offence, they mask it.
3/ Anelka foul /sending off. I can see this both ways, may have been a trip, may have been two guys simply catching feet running for the same ball, but again, Anelka has gone on a stride or two before going down. In my mind at the time I thought foul, in replay he could easily have gone on and had a clear run on goal. Why did he opt to go down - did he bottle having the clear chance?
4/ The first handball. Yes, I think that was clearly missed. Might not have been absolutely deliberate but was enough to convince me.
5/ The Eto'o handball. Can't see that; he had his back turned, it hasn't hit an extended / upraised arm, and even in replay it took a while before I was convinced it was arm as opposed to shoulder blade. That would have been incredibly hard to give and as a referee at that point of the game and competition you're only going to give the decision you are 100.0% convinced you have right.
And while we're at this point, might I point out that there are no rules of the game; it's rules of the competition, like 2 legs, away goals, etc. The game is played according to the laws, and anyone quoting the 'rules' clearly hasn't actually read the Laws.

Try reading them - you might be surprised particularly by some interpretations / IBD's
