Ferrari team principal Maurizio Arrivabene is adamant that a recent engine upgrade has moved the team forward, despite a disappointing performance in the Canadian Grand Prix.
The Italian team finished fourth and fifth in Montreal, while Mercedes dominated the entire weekend.
The German manufacturers are renowned for having the best engine, but Arrivabene insists that his team are improving.
He told Autosport: "I think the engine upgrade was giving us the positive answer we've been asking for. Unfortunately the weekend was not a good one for a number of circumstances that are in front of everybody, but the response we got from the engine was good.
"It's a long way to go. We need to have a bit of humility to recognise that at the moment [Mercedes] are stronger than us without thinking we close the gap so we can beat them every race.
"This is not realistic, honestly, but the answer that we got this weekend was quite good."
Lewis Hamilton strolled to a simple victory, ahead of Nico Rosberg.
