Jenson Button is convinced Red Bull Racing will crack if put under pressure.

World champion Sebastian Vettel has so far had it easy this season, winning three of the four grands prix to date and finishing second in the other from a run of four consecutive pole positions.

Vettel’s championship lead is such that even if the German suffered a failure on Sunday in the Spanish Grand Prix at Barcelona’s Circuit de Catalunya he would still retain top spot.

Currently Lewis Hamilton is Vettel’s nearest challenger, albeit 34 points adrift, whilst McLaren team-mate Button is 47 off the pace, virtually akin to two race victories.

After being trounced by Red Bull in Turkey 10 days ago when Vettel spearheaded the team’s first one-two of the season, it is now up to McLaren to try and turn the screw on their rivals.

“We can’t stand still, we have to move forward,” Button said.

“This team will never give up, I know that, and I have every faith they will bring some good improvements to Barcelona.

“Definitely, the Red Bulls are quick and they have a lot of points on the board, but it can all turn around very quickly as soon as you put them under pressure.”

All Button is asking for this weekend is “more pace” to compete with Red Bull on a track where they suffered in pre-season testing.

The current car has improved enormously since that disaster, but as Button rightly points out, McLaren are “never going to find two seconds from race to race”.

“We were in a bad place before the year started,” added Button.

“But you have to forget about what happened in the winter and start with what happened at the first race and move from there.

“We’re all doing our best to improve the car, but we didn’t put anything on it over the weekend in Turkey.

“Hopefully, we’ll turn up in Barcelona and we’ll have more pace. That is what we need, to get more stuff on the car as quick as we can.

“It’s something we’re obviously aiming for and hopefully we’ll make some changes in other areas as well that will help us and we’ll be fighting the cars in front of us, not just the Red Bulls.”
