There's one certainty in Formula 1: There will be winners and there will be losers. Those winners will be smiling ecstatically and the losers will be dejected, especially those, like Daniel Ricciardo in Monaco, who lose through no fault of their own.
Last year, Lewis Hamilton was the dejected one after the Mercedes team made a poor pit call and he pitted from the lead, handing victory to Nico Rosberg. This year, the tables were turned and Hamilton benefited from Ricciardo's misfortune. There was also an inspired call to stay on wets until it was dry enough for slicks - one that Hamilton took plenty of the responsibility for post-race. But was it really so inspired?
Many other drivers made an early switch to intermediates and I'm sure while Hamilton was declaring himself happy with his tyres on a drying track, Mercedes kept a close eye on what the others were up to, especially Jenson Button who normally has a good feel for such conditions.
