It was almost impossible to compare Schumacher's performance with Rosberg's; their race strategies were entirely different, Rosberg two-stopping, Schumacher three. Yes, Schumacher was able to overtake, but on faster soft tyres.
Mercedes team boss Ross Brawn said: "The softs were around one second per lap faster than the mediums and that was the decisive thing that tipped it in Michael's favour. That and the earlier safety car.
"That wiped out much of Michael's earlier time deficit to the cars in front [including Rosberg], by which time he had already got his medium tyres out of the way, having started on them and then pitted after four laps."
So the seven-time world champion got to have his cake and eat it thanks to the way the race played out, the safety car gifting him an artificially created proximity to Rosberg on track but on a tyre that at the critical time was much faster.
Looking at their respective fastest laps, set at similar stages of the race, Schumacher's was 1.1 seconds faster than Rosberg's - roughly what Brawn reckoned the time difference between the two tyre types to be
In other words, the pace of the two drivers was roughly equal and circumstances just played more kindly to Schumacher than Rosberg. Their actual performances were very similar.
