A little more from former Manchester United and Chelsea boss Jose Mourinho.

The Portuguese manager gave his reaction to Sky Sports on the death of Niki Lauda earlier this week:

"I think for a guy like me born in 1963 and in love with Formula 1, you could imagine what Niki Lauda meant.

"He's immortal from generation to generation but for us, what he represented, that's the biggest period in F1 for us guys.

"I had the pleasure of meeting him with my children and we will remember him as one of the greatest.

"I think he loved the Monaco weekend, so the best way to honour him is a great race this weekend."

Ex-Manchester United and Chelsea manager Jose Mourinho has been having a chat with Sky during the build-up to qualifying:

"It's amazing weekend and I'm a big fan." said Mourinho.

"Teams invite me here and I like to learn from other sports.

"I had the chance to sit down with Christian Horner (Red Bull team principal) a few years ago and spend a few hours with him to talk about F1 and share experiences of the sport."

Ferrari had a dispiriting Spanish Grand Prix, when they were further away from Mercedes than they had been all season. Their biggest issue in Barcelona was their lack of pace in the final sector - full of slow corners, like Monaco. And Sebastian Vettel was not sugar-coating anything when he spoke to the media on Wednesday. “We understood in Barcelona we are just not quick enough,” Vettel said.

“We are working very hard, trying to make a difference. This track is unique and anything can happen this weekend so it is probably irrelevant what the paper might say or what the form of the last five races might suggest. But certainly going forwards we know we are not quick enough to beat Mercedes but we are working very hard to try to make a difference as soon as we can.

“For here it is difficult to predict because it is such a unique place and you expected these kinds of corners don’t really suit us given the last couple of races but I don’t see why we shouldn’t have a good race. Historically, the last couple of years were very good for us. I am fairly optimistic and looking forward to getting back on track.”

If you're just joining us, the main story today has been Sebastian Vettel smashing into the wall at Turn One - Sainte Devote.

These were the times from third practice. Lewis Hamilton was fastest in sessions one and two but has to settle for third today.

Charles Leclerc gave Ferrari some much-needed encouragement with fastest time in final practice at the Monaco Grand Prix.

The 21-year-old, in his home race, was 0.053 seconds quicker than Mercedes driver Valtteri Bottas. Lewis Hamilton was third, ahead of Red Bull’s Max Verstappen. But Leclerc faces a stewards’ investigation before qualifying for speeding while the virtual safety car was deployed.

The VSC was in action because of a crash by Leclerc’s team-mate Sebastian Vettel, who hit the wall at Sainte Devote. Vettel locked his inside front wheel on entry to the first corner and rather than abort into the run-off area decided to try to make the corner. He paid a heavy price for the misjudgement.

The German made the same mistake in practice on Thursday, but got away with it, just managing to stop before hitting the barriers. This time, his front wing and front suspension were broken and Ferrari will have to try to repair the car in time for qualifying. The investigation facing Leclerc will be a nervous time for Ferrari - one possible punishment is a grid penalty.

Verstappen’s team-mate Pierre Gasly was fifth, just 0.199secs slower, the closest the Frenchman has been to the pace all season. Alfa Romeo’s Antonio Giovinazzi was an impressive sixth quickest, ahead of Toro Rosso’s Daniil Kvyat, the second Alfa of Kim Raikkonen, Alexander Albon’s Toro Rosso and Kevin Magnussen’s Haas.

We have qualifying for the Monaco Grand Prix at 14:00 BST, but we have live motorsport for you right now on the BBC.

Check out our live coverage of the latest Formula E race, the Berlin E-Prix right now over here.

Sebastian Buemi is the man on pole, and you can read a preview of the race here.

This is encouraging for qualifying later. We were all expecting a Mercedes procession, especially after Sebastian Vettel took himself into the wall at Turn One.

But his team-mate Charles Leclerc is the quickest man, and Ferrari will be desperately hoping he does not get penalised for a potential infringement during the virtual safety car period.

The rest - 2. Bottas, 3. Hamilton, 4. Verstappen, 5. Gasly, 6. Giovinazzi, 7. Kvyat, 8. Magnussen, 9. Raikkonen, 10. Albon, 11. Hulkenberg, 12. Ricciardo, 13. Grosjean, 14. Vettel, 15. Sainz, 16. Norris, 17. Perez, 18. Stroll, 19. Kubica, 20. Russell

It's a race against the clock to get Sebastian Vettel's Ferrari back on track ready for qualifying.

Kimi Raikkonen is celebrating his 300th grand prix this weekend. Well, that’s not quite true. It is Raikkonen’s 300th grand prix. But he’s treating the statistical milestone with the casual disinterest one might expect. “I tried to force them to cancel everything, but I’ve not had very good success so far,” he said.

“It’s no different from last week or the next race. In the end this is just a number. For sure it’s different from the first race but after that, once you go on for a while, it doesn’t really change.”

It is encouraging but let's not get carried away Mercedes are formidable this season but Leclerc at least for now has thrown a cat among the pigeons.

Dreamer Girl: It's no different to when other teams have been dominant for periods of time. It's down to other teams to up their game and be more competitive. Haters will ignore that fact and blame Mercedes and their drivers for the "boring" F1

Treble Blue Photography: It's all about racing. Create the best car that you can and hope the driver is up to the job. In Lewis Hamilton they have the best 'racer'. We have had plenty of times previous where one team dominates, then others catch up.

Mike Bailey: I don't think the dominance is ruining F1. If anything it is better! With two from the same team fighting for title look how close it is and likely to be all year. When two teams fight for title there always likely to have support from secondary driver to help them win!!

Not amazing from Racing Point though. Sergio Perez 17th and Lance Stroll drops down to 18th, with Lando Norris moving up to 13th.

Speaking of Stroll, he locks up, misses the turning point, goes straight on at Turn One. It's where Sebastian Vettel went into the barriers but the Canadian avoids that and into the run-off area he goes. Reverse, reverse.

Racing Point were hoping to make a step forward at the Spanish Grand Prix, as a result of the introduction of a big aerodynamic upgrade package. But it did not give them the boost they expected and Sergio Perez said the team was “worried” about that. "Our performance in Spain was very bad, a lot worse than we expected,” the Mexican said.

"We hope it was just track-related, and we just struggled in Spain. I hope we can be competitive, and back to our usual level. All season we have been struggling for pace, but I hope this weekend can be a good one for us where we can score plenty of points.”

Lando Norris, 18th overall, skips the corner but no real harm done. What of Williams? Same old, same old. They are 19 (Kubica) and 20 (Russell). How much longer can they keep going like this?

Some pace from Ferrari finally. Leclerc goes fastest, just pipping Bottas by 0.073secs. Twenty minutes to go. Be ironic if he's genuinely quick and then gets a grid penalty.

Remember, Leclerc has a trip to the stewards later on for a potential infringement during the virtual safety car period following Sebastian Vettel's crash.
