He might be Ferrari's man now, but they can't speak highly enough of Sebastian Vettel down at Red Bull. That's hardly surprising given he won four consecutive Formula 1 world championships for the team. But there's more to it than that. Like all truly great drivers, Vettel left a lasting impression.
"Sebastian is mentally very strong - he's very committed, very determined; he's very sharp, he misses nothing, so his complete package is astonishingly good," says Red Bull's chief engineer Paul Monaghan.
"He has the general things that each great driver has," adds Red Bull motorsport boss Helmut Marko. "He's focused, he's into detail. All his life is, more or less, focused on racing."
