He's way older than Kyrgios who I guarantee will have much better slam results when all is said and done. There are tons of things Monfils can't do such as having the brainpower to realize he should not try to out rally Nadal, Murray or Djokovic. I'm calling him a moron because he could be so much more and his tactics absolutely SUCK. I very much enjoy watching him play when he does it the way he should, that is using his great shot making skills and ability to hit blazing fast winners. But he hardly ever does that. So moron it is. A guy with great aggressive skills should not play like a pusher. And if he's so supremely talented why is he tanking matches so often? Surely a talented guy wouldn't do that, he'd win them and have the grey matter to know how to play and that means NOT pushing the ball.
