I can, but saying "today we end this" considering the fact it wasn't planned at all, I won't say it's stupid 'cause I won't insult you (no reason for insulting, insulting is stupid, etc.) But it's simply impossible. Some people planned other things for after the matches, in French team for example, but I'm sure in other teams there are many people that planned other things.
So if you want to speed this up, very well, but put semifinals and finals on tomorrow, so at least everyone has one day to prepare, and it'll be good. 'Cause actually, saying "we end it in 5 hours" it's nonsense.
