Fernando Alonso set the quickest time in final practice as the teams gear up for the crucial qualifying hour in Monte Carlo.
The Spaniard set a fastest time of 1:15.164 around the twisty street circuit after switching to the super soft tyres in the closing stages, pipping Jenson Button by a mere 0.069 seconds.
McLaren continued to run strongly with Heikki Kovalainen in third ahead of Rubens Barrichello, while Lewis Hamilton set an impressive pace on the longer runs before winding up in seventh place overall.
Ferrari also appear to be back in the hunt with Felipe Massa and Kimi Raikkonen in fifth and sixth place.
A mere two tenths of a second separated the top seven drivers paving the way for an epic scrap for the first rows of the grid in qualifying in less than two hours time.
