I think a red card (and subsequent absence from the next game) is enough for punishment. The fact that Mourinho talks a lot is part of the show (and actually it's not so bad for football as a business) and it seems to me that if the functionaries are serious about his every word (even unfair) then this will cause more suspicion and rumors of foul play , referee conspiracy, etc.
That might be a good show for the league itself, but even for business, there is a line that shouldn't be crossed. By that baseless accusation he said in that game, then it means that he doesn't respect his opponent, by saying the match was fixed and in the other words, Cremonese shouldn't win. I saw the match and Cremonese deserved that win.
It has been a long time since Roma beat Juventus the last time no matter it is a home or away game. This is a point to consider I think before making a bet on the game.
Of course Juventus were better than this season back then mostly. But in fact Juventus are maintaining a good series in the league lately also. They have made their winning streak four games with the win against Torino. Honestly this is going to be their toughest game these days. Roma are far ahead of them and they are having a decent season now. They just surprise us by simple point losses against smaller teams lately. For example their Cremonese game ended very unexpectedly. But I think Mourinho will prepare his players specially for the Juventus game.
I will bet on both teams to score here and not bet on any side to win.
Actually Roma aren't far ahead of Juventus based on performance, which if we refer to the normal point and ignore the point deduction, currently Juventus should be on 2nd position in the table with 50 points, 6 points ahead of Roma.
From my own research, the winning percentage of Juventus in their away games is 6/11*100% = 54.5%, while in the other side, the winning percentage of Roma in Olimpico is 7/11*100 = 63.6%. 63.6% isn't an ideal number for home game, which it's a clear sign that Juventus chance to win the game is quite high. However, your prediction is quite fair by picking both team to score.
As reference, here are the odds of both team to score in this game;
Coinplay = @2.02
Sportsbet = @2.00
Rollbit = @1.98
It's a fair bet I'd say.
