You say you can't be sent of for preventing a goal scoring opportunity after a goal is scored (and I agree) but that means that whether or not a keeper (in this case) gets a red card is entirely up the actions of Eto'o's teammates. If a Barca player hadn't have continued to run on to the ball that Eto'o pushed wide of Lehman then there would have been no advantage and, ergo, automatic dismissal, right? The logic of making what happens *after* a foul the arbiter of how 'bad' a foul is strikes me as vaguely non-sensical. I'm not saying that you're wrong because with the current rule, the way it is worded, you're absolutely correct, it is just strange to think that a player's dismissal hinges upon neither the player he fouled or himself, only upon whether or not there is 'coincidentally' an 'advantage' to the team fouled.
It seems like it would make more sense to simply allow advantage and punish the foul afterwards with the same penalty regardless. If you prevented a goal scoring opportunity on the player with the ball that you fouled, then
Basically, if the ref wants to play advantage and Giuly trips instead of putting it in the net before he even gets close to the ball so the ref decides there is no advanatage, the keeper is off.
Of course, if it is going to be a bit unfair, it certainly should be against the person committing the foul.
