I couldn't resist, I already watched the video during the match and it is AWESOME!
The beginning is totally "tongue in cheek", the rest is completely different and very sincere.
He was apparently feeling so bad a few months ago, Champion keeps hinting at how bad it was. And he's still struggling badly in training, losing his joy as soon as he enters a tennis court, being completely negative...
The last training session with Champion is very interesting, I had no idea he was still feeling so down, poor boy!
