Thanks to Fiddes blogg, I just found a very nice interview with Robin and Magnus on the site of Swedish television.
Unfortunately there is no direct link, but if you go here
http://www.svt.se/svt/jsp/Crosslink....port&from=menu and then to "Senaste i SVT play" and click Tennis there, then you just have to take the report on the top of the page
It is about that Robin aims to become a Top 10 Player as soon as possible and Magnus has said he will stop working with Robin directly, if he can´t control his temper.
