Jimmy Vicaut provided a timely reminder to his rivals ahead of next week's European Athletics Championships in Amsterdam with two stunning performances this weekend.
Having equalled the 100m European record of 9.86 last month, Vicaut, 24, took the French Championships by storm in Angers on Saturday.
First he produced a 9.94 in the heats and then he won the national title for the third time with 9.88.
On a weekend where a number of European sprinters ran superbly, Vicaut was the best of them all.
He will go to Amsterdam looking for the first major outdoor title of his career.
The 2013 European indoor 60m champion won 100m silver in Helsinki 2012 but he is running so well, with his 9.86 still the fastest in the world this year, that he will be among the main contenders at the Olympic Games aswell.
His 9.88 is the joint second fastest time this year, sharing that mark with Olympic champion Usain Bolt.

It was the fourth occasion he has broken the 10-second barrier this summer and with this speed and background, when he is pushed even more in Amsterdam and then in Rio, the European record he shares with Francis Obikwelu will surely be under threat.
Vicaut is not doubling up with the 200m in the Netherlands but he won that French title on Sunday in 20.62.
Christophe Lemaitre, the double European 100m champion, ran 10.09 in the 100m heats but missed the final after sustaining a small injury.
By his normal sensational pole vault standards, it has been a fairly quiet summer for Vicaut's French teammate Renaud Lavillenie.
Yet he is coming to the boil just in time for Amsterdam where he is chasing an amazing fourth successive European crown.
Before Sunday in Angers, he was third in the world with a best of 5.83m twice but now he is top of the list after winning the French title for the fifth time in a row with 5.95m on his second vault after first-time clearances of 5.75m and 5.85m.

'I had to be confident and powerful every time,' said Lavillenie, speaking to L'Equipe as he reflected on his triumph where Kevin Menaldo was second in an impressive 5.80m, the third best by a European this year.
But there was despair for Teddy Tamgho, the 2013 world champion, after he won the triple jump with 17.15m. On landing in the sand, he fractured his femur. He had to be taken off on a stretcher and could be out for six months.
Since winning the European junior 100m title in Rieti 2013, Stella Akakpo has made the podium in the years that have followed and she will be eyeing more success in Amsterdam.
A relay silver medallist in Zurich 2014 and European under-23 bronze medallist last summer, she won the national 100m title in 11.17 from Floriane Gnafoua (11.20).
Among the other French champions, Floria Guei took the women's 400m (51.19), Cindy Billaud was first in the 100m hurdles (12.83) and Melina Robert-Michon threw 63.40m for victory in the discus.
