Spanish Grand Prix: Five things we learned

Major concerns Toto Wolff admits Mercedes are worried

Major concerns Toto Wolff admits Mercedes are worried

Four-time world champions Lewis Hamilton has revealed that even the Mercedes' top bosses want to see his contract extension.

But let's hear what Mercedes team chief Toto Wolff makes of the alleged Pirelli/Mercedes collaboration theory?

As for his future, Mercedes have reported that Hamilton is on the verge of re-signing with the Brackley squad.

On the heels of three consecutive pole positions for Vettel, the battle between F1's leading teams Ferrari and Mercedes swung dramatically in favour of the latter at the Spanish GP - as the Silver Arrows locked out the front row and finished 1-2 in the race.

"I think there's been quite mixed races and the end results haven't been really I feel sometimes quite there, that I feel would have been possible with the pace we have", declared Bottas.

On the face of it, Lewis Hamilton not only won in Barcelona - his second victory on the trot - but thrashed the opposition, pulling the trousers down of not only his team-mate Valtteri Bottas, whom he beat by over twenty-seconds, but his title-rival Sebastian Vettel, too.

It was the first one-two of the season for Mercedes, which had struggled to keep pace with the Ferraris.

"So it's a good feeling".

"I think it's pretty straightforward", Vettel said in the paddock after testing. He has some serious records. Seventeen championship points is a healthy cushion, but Hamilton may very well need it if he suffers another horror show in the principality. "It's hard to beat all of these records that he has".

"This weekend we got ourselves on the right path", Hamilton said.

In Spain on Sunday he followed race victor Hamilton in the team's first one-two finish of the campaign, albeit 22 seconds adrift on very worn tyres after a massive 47 lap stint on a single set. "I would like to hope it could be part of the turning point". Hamilton set blindingly fast sector times throughout the race regardless of tyre-type, and it is going to be dashed hard for Vettel to claw back this advantage.

Vettel started well in Spain, making an outside pass on Bottas on the first turn. Carlos Sainz (Renault) and Fernando Alonso (McLaren) secured seventh and eighth places respectively.

Charles Leclerc of Sauber and Sergio Perez of Force India closed out the top 10. "I just need to continue my development, there's never things that you can't learn more".

"Of course we do not want to lose him, but I also believe that he doesn't want to go somewhere else". 'There's a nice story and a nice harmony there, but when I was told, being a relatively new Brit, that the weather is sub-optimal in April, they warded me off that quickly.' The honour of the 1,000th race will fall to the desperately soulless Shanghai International Circuit in China instead.
