Exhos are different compared to a few years before. The players do take them more seriously. If you saw Rafa's reaction at the end, you'd know that he wasn't happy about losing that much. I also didn't see a lot of smiling and humour between the two during the match. That was intense, make no mistake!
Just what I pointed out earlier and the comms also said that exhos are more important now. Rafa certainly was not happy as he said it was not good enough.
