The Australian, now a member of the works Porsche team in the World Endurance Championship, says that Ferrari's season has been disappointing so far as the Italian outfit still has its work cut out for itself in order to dispute Mercedes current supremacy.
"They're making ground on Mercedes," Webber said in an interview ith Germany's Auto Bild. "But they still haven't caught up yet. They've had a good race here and there, but Mercedes still remains unbeatable. And Red Bull is now ahead of Ferrari."
"Sebastian and Kimi are doing their best. They're protecting the team a lot when they're speaking to the media, but they also know that the team needs to get better.
Webber believes that Vettel, his former team mate, is a great asset for the Scuderia as he can galvanize the team's forces and push it forward.
"He can do it but he needs the right people and I'm not sure if they have them at the moment. Ferrari is under constant media pressure, always needing to deliver.
"You can see with Sebastian that it can be frustrating, but his experience will help him."
