Enough is enough. Pirelli have to change their tyres after a race bordering on a farce

There was much negative reaction both during and after the Spanish GP from many fans.

Even Red Bull struggled. This really surprises me because watching out on track the car looks very good, especially with front grip. Red Bull is convinced this is because their car has so much grip that the tyre simply can't handle it. Christian Horner told me that it was midway through the second stint when they realised a three-stopper was impossible. They had to stop Webber four times anyway to extract him from traffic after a bad start and that worked well. McLaren had a split strategy but their two cars ended up line astern, although only after Sergio Perez had been effectively told to hold station. I hope they can find a solution for their car and that we won't hear the words 'we've decided to focus our resources on the 2014 car' too soon. The fact that they increased their record-breaking run of 63 consecutive points finishes will be little true comfort. Most random fact of the day is that Esteban Gutierrez, who started 19th and finished 11th, led the race for two laps and completed the fastest lap of all. Which confirms that there is some potential in the 2013 Sauber to be teased out. Paul di Resta had another solid race to be first Brit home, and it's a pity that he couldn't launch a late attack on the works Merc of Rosberg. Next up is Monaco, which couldn't be a more different track layout and demand to Barcelona if it tried. Let's see how the dice roll there. MB
