Simon need to go on vacation and sort himself out. He really hasn't been himself in a long time.
he's probably tired from all of these years of pushing
let's be honest, tennis is a fun sport, but when you watch Simon play do you think he looks like he's having fun? his game style is so much hard work, it's not nearly as flashy or enjoyable as some
I'm not surprised he might be losing a bit of passion for it
