Vettel says super softs working well

The softest of all the compounds raced by Pirelli so far is making its grand prix debut this weekend, and there were concerns that they would degrade too quickly.

Vettel, however, completed 23 laps with them in the second Friday practice at Monte Carlo, and admitted they were lasting well.

"I think not bad, it's been positive so far," said Vettel, fifth quickest today, of the tyres. "Both tyres are working and that is most important thing, and lasting pretty well.

"We will see how the conditions are on Sunday. If it's similar to today then the super soft seems to be preferred tyre for qualifying. You can extract most time from it, so no dramas today."

The Red Bull driver, quickest in the morning session, said he was pleased with his day, although the admitted the track was bumpier than before.

"I think we had a good day so far. Obviously it was important to do a lot of laps here and I had a good feeling straight away. It is fun around here.

"It is a different track, very bumpy and very rough, and some places on the track they have resurfaced but I don't think they have made it better. It is even worse. It is interesting.

"Ferrari looks very competitive but all in all everyone is really close to each other."

Team-mate Mark Webber said he was satisfied with the super soft tyres too.

"It was alright. Similar to all the Pirellis actually," he said.

The Australian, however, lost all the morning session after a problem with his car's gearbox.

"We missed 40 laps this morning and you are not going to get that back overnight, so we need to get back into the groove a little bit on Saturday morning and hopefully we can get back in business on Saturday afternoon, and then recover."
