Nobody knows reigning MotoGP champion Marc Marquez be🐲tter than his younger brother Alex, the pair spending much of their lives together away from the track as well as being team-mates at Repsol Honda.

But even Alex was stunned by Marc's performance in Sunday's Spanish Grand Prix s♏eason-opener, despite the disastrous end.

Marc had taken the ✱lead from Maverick Vinales on lap 3 and was pushing hard to escape when he suffered aℱ massive front-end slide through the Turn Four left-hander.

The Spaniard saved it with his elbow but a high-speed trip through th🙈e gravel saw him re-join in 19th place, 9.3s behind Vinales.

"When y💎ou have a brother and something like this happens, for sure it affects you a little bit. But we know that Marc is strong, we know that Marc will come back," said Alex, after finishing his first MotoGP race in twelfth place.

"Today, I think he again gave a demonstration of why he is the champion and why he is oneꦆ of the best riders in the world. He did an unbeliev🐠able race.

"He was in front of me when he cam🌠e back out of the gravel and in three laps he had disappeared. S🎶o I said, 'wow, he will make a good show for sure again today'.

"But I didnꦑ't expect that when he crashed he was already up to third place. I thought maybe he was in seventh, eighth. Something like that."

The reigni🐓ng Moto2 champion added: "If you take Marc's data from today, every rider would be destroyed. Because he's unbelievable. He waಌs unbelievable today.

"I thin⛄k all the riders here in the paddock will know that today he was the winner of this race, because he was unbelievably fast."

Ma🔯rc will now undergo surgery to plate or pin&n꧂bsp;the arm fracture on Tuesday and is almost certain to miss this weekend's second Jerez event.

"This can happen.💙 We are humans. Everybody can be injured, and I hope that he will come back really soon and stronger," said Alex.

💎Petronas Yamaha'sꦚ Fabio Quartararo went on to claim his first MotoGP victory on Sunday, by 4.6s over Vinales.
