It is an annual, pre-emergence is a chemical that stops seeds from germinating (google it)

it doesn't work i tried with old roundup version (with glyphosate that is now forbiden in france) and even with that it comes back (with 2 applications , 3 weeks between them)
I even tried acid! it came back!

Gly only works on actively growing plants. It can't be dormant. You could have missed some and there may have been stolons or rhizomes that didn't get killed. You may just have to keep at it.

you mean that applying gly at winter is useless?
i planed to scarify it hardly in 3 weeks i hope the reseeding will help
