Credible computer ratings have a role to play in informing us of a player's ability. After all it's simply an opinion of a fan. We of course can't be sure if he/she would provide an unbiased opinion, but in that case let's just give up reading other clubs' message boards. (Not that I do that shit except for major enough events.)
Not sure why you're shocked. Did you think that all those years of happy and cheery "public" persona means that his private live must be the same way all of the time? He's probably finally 'cracked' from the expectation and pressure that people/society have on each other. (i.e to be happy and to confine sadness and your problems to your self or just to your partner and closed ones.)
Not sure if there will be too many bookings due to it being a friendly and the players's solidarity.
I fancied BTTS and no booking at 12/1 - but I didn't bet.
