never go all in...and never go all in for a real or barca team in the first match of a group stage. I don't think Madrid fear Dortmund or Ajax so a draw here would not be a big deal and they are coming off a brutal game, City proved nothing in CL last year but 1 year experience could go a long way this year.
To me Real win by 1 and most bets will be voided but it's the biggest match of the day but also one of the tougher ones...no bet for me even with a gun to my head.....
