 And Isaac, we've had a message in from Tess in Minneapolis who says, why does it matter if the crowd was booing anyway? Why would they only do it on a point he had lost? Does Novak think only he should get to express himself? Yeah, that is the question. We shall find out a little bit more about that story later on because it is a very strange mentality, perhaps something to pump himself up as he looks to equal Roger Federer's record of eight Wimbledon titles. Isaac, thank you.
