Thursday morning set the Monaco weekend up as a battle between Fernando Alonso's Ferrari, star underdog Robert Kubica's Renault, and the Red Bulls.
It was Alonso who emerged in front in the first session, but by only 0.073 seconds over Sebastian Vettel in the Red Bull, and with Kubica just 0.016s further back. The 0.4s gap to Mark Webber in fourth was largely due to traffic, too.

The McLarens were back in a low-key seventh and eighth, sandwiched by the Mercedes.
