Well, true. Though Drogba's 36, Essien's 33 and Odemwingie (who I was going to mention in my original post, along with Ameobi, but thought it might be stretching the definition of a great player!) is 32. I had counted them in the first team, but it seems they've dropped off enough not to be considered for the first team, which, coupled with how poorly the African teams have done so far, could be taken as strengthening my point.
Boateng is an interesting one as he quite after the last World Cup and only came back for the second leg of the play off! I wonder how that went down in the Ghana camp.
It's true that it's a bit of a stretch to group them all together, and I don't expect them all to have the same fate. You're right that Ghana's goal was lovely, and of course Ivory Coast (who have way more than their fair share of 30+ stars) deservedly won their game. But Ghana and Ivory Coast in particular came from relatively nowhere to fairly impress at the last two World Cups, having never previously qualified. Now we see them with ageing squads not doing as well as four years ago. Football often comes and goes in waves, and teams in particular; we've seen that ourselves, when a small country in footballing terms has a golden generation, and then drops off as those players retire, not to be adequately replaced.
There's time to go before 2018 of course, but who's going to replace those players, who are mostly genuinely world class? Or are we going to see returns for the likes of Morocco, Tunisia, South Africa or Senegal? Or maybe a new country emerge, like Egypt (well, not entirely new, but it's been 24 years), Ethiopia or Burkina Faso?
