Free Practice in Barcelona may deliver more action than we have seen on Fridays of late, as Pirelli are offering up an experimental set of tyres to try and encourage teams to do more running during each ninety minute session. The teams will also want to push their cars as much as possible, as they bring a raft of updates to the cars, now they have the benefit of being back in Europe. Friday isn't going to tell us too much about who is doing well, but we may get a hint of who has got it wrong.
