Freaky - Federer just beat Krajinovic in Miami and forgot who could have beat Medvedev in Indian Wells
It seems to be a certain Krajinovic.

Is padel threatening tennis? Inside the revolution shaking up the established order 
2) why use "could have"? It actually happened already. Just omit those two words.
3) it doesn't "seem to be" anything. It WAS Krajinovic.
4) what is Krajinov certain about?
5) why is the admin even responding to me on the app? Pro tip: as a writer and content provider, don't engage with your audience. You get it?
Before all, why make sure to be so rough and unpleasant in your post ?
So first, take it easy, we are just discussing to try to understant better each other. So don't see any agressivity in my previous message. All is cool and relaxed here.
Second, most of TT writers are French so it's obvious that sometimes we can make some misinterpretation. But it doesn't matter, some nice members can notice it and so we will be better next time. Don't think too much about failure, the much you try, the better you will be and the nicer and funier your life will be.
Then, about your questions.
1, 2, 3 and 4 are totally pertinent. So we will think about it to correct this Flash and to be better in the next ones.
To answer to the 5, why are asking for questions if you don't want any answers ? In my opinion this is very good to interact with people that you call "audience". You don't need to hide and protect you're image to stay credible. Unless you have something to hide of course. On TT, interractions between eveybody is one of the main goals. So, as anybody on the website, pro writers do it too when they feel they would like to. The ambiance is much more pleasant like that. So why don't just be happy that we consider you and everybody enough to interract with you ? Do you prefer we us to ignore you ?
Whatever, good day, good interractions and good tennis to you and to everybody on TT ;)
