Formula One returns with the start of the European season, perhaps, or at least a return for the giant motorhomes gracing the paddock. If you're not too busy trying to spot who has the tallest tower, then it's time for the first 90 minutes of Free Practice action.

We're expecting quite a few upgrades from teams as they've had a moment to think about which direction to take their cars.

Free Practice 1 should get underway at 8am GMT+1, which is 10am local time, but keep your eye on the weather!

One to Watch

It'll be a good idea to keep an eye on Williams, as the team are undergoing some rather dramatic changes. We already know that Sam Michael will be leaving at the end of the year, which is bound to change his outlook on things a little, no matter how professional he is.

Meanwhile, Rubens Barrichello has defended him, equally altering his own position within the team somewhat:

Sam is doing five or six jobs, so he's overloaded," explained Barrichello. "It's too much for a single human being. He ends up achieving only half of his own capability doing his own job because he's overseeing other things... I would have liked to get consulted as well. It's something that needs changing – Williams needs to work as a family, not keeping things to themselves and going to the press.
