Good morning everyone, and welcome to Eurosport Yahoo!'s live coverage from Free Practice Three ahead of the Spanish Grand Prix.

After all the posturing, it's qualifying next. That starts at 13:00 UK time - and you can follow it all here on Eurosport Yahoo! Thanks for joining us.

The two Red Bulls end the timesheets more than a second clear of the field. Ferrari looking a bit off the pace and McLaren and Mercedes some way off the pace. There's a suspicion that McLaren might have a little bit more up their sleeve than they showed this morning - but an extra second and more? Surely not.

Vettel quickest! Outrageous! 1:21.707, just a touch quicker than his team-mate and that's not a bad effort when you've spent most of the morning in the garage...

Session over - just enough time to finish the laps you're on, guys...

Vettel out on his flying lap - and he's right on pace with Webber...

Schumacher out for another quick lap - no improvement, but he's gone quicker than his team-mate Rosberg in this session.

Here comes Vettel - there should be time for just one flying lap.

A footnote to Webber's blistering pace - on his third full lap he set the fastest times in sectors one and three, but was a little off the mark in the middle sector which prevented him from extending his best.

Alonso back in the pits. Maybe he's just not happy with his car after all. Some worried-looking engineers having a look under his car.

Button up to third, but he had more pace than Schumacher given he had to shuffle through traffic on that lap. Hamilton, in similar circumstances, just a touch quicker than his team-mate.

1.2 seconds the distance between Webber and Schumacher. The Ferrari may still be playing it cautiously and the McLarens are likely to be the only possible challengers in a qualifying situation. Jenson Button now out on track.

Webber top - 1:21.791 - that's faster than anything we saw yesterday - a stunning lap from the Australian.

Alonso in the 1:24s - but is he running heavier fuel?

A hint of how this could go - Alonso just outside Schumacher's first-sector split, Webber already three-tenths inside it...

Alonso starts his flying lap. Webber is just five seconds behind on the track.

And not far behind is Webber in the Red Bull, also on the option tyres. No sign of Vettel moving as yet though.

Speaking of which, as we move into the final ten minutes, here comes Fernando Alonso.

Kovalainen up to 12th in the Lotus with a very decent run - there are plenty of cars on option tyres still to head out, however.

Heidfeld's Renault finally arrives into the garage after the fire.

Kobayashi tests out his Sauber on option tyres - Perez has managed to put his Sauber fifth but the Japanese outshines him, just six-tenths behind Schumacher and into third place.
