Daniel Ricciardo is hopeful there is "one magic button" which can transform Red Bull's Formula 1 fortunes after another difficult race in the Chinese Grand Prix.
The Australian finished ninth after a mistake with his start dropped him from seventh on the grid to 17th, while team-mate Daniil Kvyat retired with a Renault power unit failure.
When asked if Red Bull's major aerodynamic upgrade coming at next month's Spanish Grand Prix could be the magic button to help close the gap to the frontrunners, Ricciardo said: "I think so.
"I think there is one magic button, we've got the people behind the team to hold the magic button and I hope that's the one.
"I don't want to get too caught up in it, because it's easy to get disappointed, but the team has got the ability to make a big step like that.
"Seeing that Ferrari's done it only means it's within reason that we will able to do it as well."
The Milton Keynes-based team is fifth in the constructors' championship, one place behind Sauber, which finished last in the 2014 standings having failed to score a point all season.
