Ferrari boss Maurizio Arrivabene says Kimi Raikkonen's performance in the Bahrain Grand Prix was "absolutely spectacular".
The Finn finished a distant second to Mercedes' Nico Rosberg in the race, equalling the result he achieved in last year's event at Sakhir.
Raikkonen had to fight back after making a poor start in which he dropped down the order from fourth on the grid.
"I think the way that Kimi drove during the race was spectacular, absolutely spectacular," said Arrivabene after the race.
"If you look at at the overtake around the outside of Ricciardo, he reminded me of the driver from the old times.
"It was very, very good for me."
Arrivabene revealed, however, that the reason for Raikkonen's poor start was that his hand had slipped from the clutch paddle.
"I heard that most probably the finger slipped on the paddle," he said. "It's something that could happen and he got a lot of spin and lost a bit of time. But what he did afterwards was unbelievable."
Teammate Sebastian Vettel retired from the race even before the start, after suffering an engine problem during the formation lap.
Arrivabene said the problem was different to what had put Raikkonen out of the Australian Grand Prix two weeks ago.
"It looks like a valve or a piece of the injector. This is what I heard 10-15 minutes ago. They need to inspect the engine and see.
"Kimi was the turbo. Nothing to do with this."
