In Formula One, times change, personnel move on, partnerships are broken and new alliances formed. Yet there are some factors that never change. One is that passing at San Marino's Imola circuit is almost impossible for modern F1 cars.
Another is that Michael Schumacher will not be denied for any length of time. A third, and one that has become increasingly apparent over the last season, is that reigning champion Fernando Alonso will take whatever the opposition grant him over any given Grand Prix weekend.

It was these three factors that combined to provide the story of Sunday's San Marino GP. On Saturday, Schumacher rewrote history again, setting a new world record of 66 pole positions - poignantly, on the very circuit where previous record holder Ayrton Senna had set the final pole of his career.
Come Sunday, Schumacher had other goals in mind. Throughout his record-setting career, the seven-time champion has never come up against an opponent who consistently got the better of him in head-to-head clashes - until Alonso.
