Heading into the season, Ferrari were widely believed to have the strongest package on the grid, but the Scuderia have yet to climb the top step of the podium this season, although Charles Leclerc came extremely close in Bahrain before having a dramatic engine failure.
"Ferrari are fighting Red Bull, who have a Honda engine, Mercedes are on another planet!" Briatore communicated on his Instagram account.
"This [Barcelona] is a circuit that tells the truth, if you go wrong here you can't compete for the world championship.
"It will be difficult for Ferrari to win a few Grands Prix, but it seems to me, hearing the interviews, that everything's going well. That's motivational."
