I really feel for him.
Coming from arguably a career high last season (on par with the treble season before), and widely considered one of (if not the) best and most influential players in the world, to being ruled out for the season six games in, with a major knee injury in your absolute prime (and all of the doubt and worry that will bring, even after he recovers).
Many of us have gone through this—albeit at a much lower level, with far less support, both in quantity and quality—and will know how difficult it can be.
But he is a person that is generally quite sensible (pissed up singing aside) and, with the help of the club and others, I am sure he will get through this and come out the other end stronger for it. Better still, this is an in between year for international tournaments, so on a personal level, if it had to happen, this was best timing.
And, luckily for him, his game has never really been based on pace or agility, which is usually what is hit hardest with ACL and meniscus injuries. With proper surgery, rehab, and strength training, he should be back to his full compliment of attributes that saw him become one of the most dominant players in the world (and definitely one of the best DMs to ever play the game).
