I don`t think it was wise of Alonso to make a move like he did when you have downshift problems. Maybe the team told him it was going so he thought why not, i reckon he should have just held station behind Button and if he made a mistake take the place.
Maybe the stress put on the engine braking so late, coupled with the downshift problem caused something to pop that wouldn`t have done otherwise. You never know, at the end of the season a couple of points could make all the difference
