I think he'll score Chelseas' only goal as for the amount of times he goes down will be higher than the amount of minutes on the ground... about fifteen.
(i) Drogba on ground = 5-7 minutes
(ii) Drogba will not score - he will be crowded-out by Bayern Munich defenders.
(iii) Final score Bayern Munich 2, Chelsea 0
Chelsea had a surprise strategy. Drogba to stay on his feet all the time, so he could be there when a penalty needed to be conceded. This would so unsettle the opposition that they couldn't shoot straight.
Think he only limped off once, and that was an injury, apparently.
