Ferrari admit that in hindsight the decision not to pit Fernando Alonso in the latter stages of Sunday's Canadian GP was the wrong one.
Fighting with Lewis Hamilton and Sebastian Vettel for the victory in Montreal, Ferrari opted not to pit Alonso, instead hoping his second set of tyres - tjhe softs - could carry him through to the chequered flag.
McLaren, though, did pit Hamilton, dropping him over 14 seconds behind Alonso. With Hamilton fast approaching Red Bull called Vettel in, a move that initially raised eyebrows.
But as Hamilton came storming by Alonso and Romain Grosjean and Sergio Perez, a very late one-stopper, Alonso fall off the podium. He was also overtaken by Vettel, finishing P5.
"With hindsight you're always right but today a podium would have not been possible," Ferrari said on Twitter.
"If ALO had pitted when VET did, maybe we would finish P4.
"Tyre degradation was the key today. It is the area where we have to look very carefully."
