Duplantis joined French Lievin after jumping on the world records 6.17 and 6.18 in the last two competitions. The 20-year-old made an attempt to polish the record by another centimeter, but had to settle for 6.07 as the victory result.

"I'm almost glad I didn't break the world record tonight because it got so crazy," Duplantis told SVT Sport afterwards.

- Now people know that I can't set a world record in every competition. So that's good. I have that pressure on my shoulders. I can jump high but not set a world record in every competition. But how can I complain when I jump 6.07, over six meters is good.

But those closest to Duplantis, the coaches and parents Helena and Greg Duplantis, believe that the son has higher heights in him - and that he strikes at the Tokyo Olympics.

- Now he is going to rest a little, and then Helena will give him a training program just like she usually does. There will be a bit of physical training and some hope that if he can get even stronger and faster for the outdoor season and the Olympics. Then hopefully he can jump a little higher, that's the plan, says Greg Duplantis.

It sounds incredible.

- Yes, but I still think there may be a higher level at the Olympics. I think so.

What do you expect for heights at the Olympics?

- I do not know. But higher!
