Jarno Trulli set the pace in today's final practice session for Sunday's Monaco Grand Prix.
Renault driver Trulli ended a crash-littered session on top with a best time of one minute 17.429 seconds as he leapfrogged David Coulthard with just seconds remaining.
McLaren's Coulthard held second place ahead of Williams drivers Juan Pablo Montoya and Ralf Schumacher as the top four enjoyed running on Michelin tyres in the sunny conditions.
Bridgestone-shod Ferrari drivers Rubens Barrichello and Michael Schumacher, who had been the quickest two drivers in the opening session, were fifth and sixth respectively.
Renault's Jenson Button, Jordan driver Giancarlo Fisichella, Heinz-Harald Frentzen of Arrows and Sauber's young Brazilian Felipe Massa completed the top 10.
