Ferrari won at Silverstone, home track of the Mercedes team, and publicly delighted in the fact. But Mercedes paid that back by winning at Monza - Ferrari's back yard.
Ferrari was that little bit faster than the Mercedes, and on home turf it occupied the front row, which meant the tifosi came in their droves on Sunday. Unfortunately, they didn't all have reason to stay until the chequered flag.
The real reason for this was yet another mistake from Sebastian Vettel. He's made a few significant ones this year. In Baku, he locked up and went off while trying to take the lead from Valtteri Bottas. At Paul Ricard he rear-ended Bottas at the start, then he crashed out of the lead at Hockenheim - handing victory to Lewis Hamilton.
