McLaren CEO Zak Brown on the future of Fernando Alonso: "We are starting to talk about it. He is really enjoying his time at McLaren now and now he just needs to decide how much longer he wants to do this. He has been in F1 long time, he is enjoying sports cars. I think we will make a decision with him sometime in the summer."

NFL star Tom Brady, asked by Jennie Gow how F1 compares to NFL: "Good question, equally as chaotic. This is my second experience of an F1 race, I was in Montreal a couple of years ago.

"Daniel Ricciardo has a great chance today, he is on pole. Should be a great race today."

Mercedes team principal Toto Wolff: "You can have a good race in Moncao and be lucky or you can be very unlucky. Hopefully we are on the good side.

"These tyres can last between five and 15 laps. We have to see what the strategy is."

I always like to get in the car as late as possible because it gets quite hot and quite claustrophobic. I would go and have a banana.

Miranda Lane: Can't wait for the best street circuit race in the world!! Let's go Monaco. Cheering Dan the Man Ricciardo for the Win. He so so deserves it! Top of all sessions!

Jeremiah Kariuki‏: Verstappen is damned if he does and damned if he doesn't. To get to points position, Verstappen will need to be aggressive. If he crashes, hits the wall or get caught in tangles, he will be damned. If opts not to be aggressive, he will still be damned.

Max Verstappen, who starts from the back of the grid: "We have to try and go forward, it will be really hard but will just try to have a clean race."

Attack, attack, attack? "Not necessarily. I will just try to do the best I can."

And this is how things sit in the Constructors' Championship. Red Bull were hoping to end the day a lot, lot closer to Mercedes and Ferrari, but Verstappen's prang will have lessened expectations dramatically.

Five races gone out of 21 this season and Lewis Hamilton has a 17-point lead. The top six is filled with the six you would expect with Fernando Alonso in the "best of the rest" spot.

He only picked up 17 points all of last season, but has nearly that doubled that after less than a quarter of the 2018 campaign.

At the bottom only Sergey Sirotkin and Romain Grosjean have no picked up any points, with Grosjean failing to finish three of the opening five races of the season.

I enjoyed the moment with the marching band, it really felt like 'yes, this is Formula 1'. That is all done now and it is about the race. Lots to do, lots to think about and we haven't got long now until the race starts.

So, strategy. A one-stop is the fastest race, and everyone will be trying to do one. The question is how. The top 10 have little choice - run the hyper-softs as long as possible and then switch, probably to the super-soft, although some may try the ultra. How long will the hypers go? Pirelli says 15 laps. Which probably means well over 20. The big question is also how well the hypers will go - ie how much pace will they lose as they degrade?

Can the front-runners pull enough of a gap on the chasing midfield pack to drop into, or will they come out behind slower cars, and if so how will that affect the race. The choice is likely to be even tougher for the likes of Esteban Ocon, Fernando Alonso and Carlos Sainz, sixth, seventh and eighth, whose cars don’t have the pace of the top three teams. Outside the top 10, the most likely choice is ultras for probably 30 or more laps and then super-softs. But some will undoubtedly go the other way around.

A win in Monaco means you don't mind too much when one of your fellow drivers decides to pour champagne right into your face. It was a Ferrari one-two last year with Sebastian Vettel and Kimi Raikkonen first and second.

Daniel Ricciardo, second in 2016, came third last year.

Lewis Hamilton has some work to do if he is to win this race for a third time after successes in 2008 and 2016.

Earlier this week he was remembering the first of those victories, which also came against the odds.

Red Bull team principal Christian Horner told 5 live: "The main focus is on Daniel getting the best result today. We've got to be sharp and on it today.

"Max has had a rough ride with the first six races, we've had quite a few mistakes,he is very aware of that. We just have to regroup and think is there anything we can do differently when we approach a grand prix to avoid the issues he has had so far."
