This weekend, at Monza, round 15 of what is rapidly becoming a marvellously gladiatorial 18-round World Drivers' Championship bout, all eyes will be on Fernando Alonso and Michael Schumacher.
But, above all, they'll be on Michael. Even if the 2006 Italian Grand Prix ends up not being his last Formula One race in front of the ever-passionate Tifosi, Schumi's every move will be scrutinised for signs that it will be.
Was that the trace of a tear in the post-qualifying press conference, we'll ask ourselves? Did he wave to the crowd rather more energetically than usual in the drivers' parade? Did he hug Jean Todt on the victory podium even more homoerotically than usual? These questions, and others like them, will be whispered up and down the paddock, and in sitting rooms all over the world.
What few F1 fans will be doing is watching Pedro de la Rosa. But, in truth, Pedro will be almost as fascinating to watch.
