This game is hardest game for Roma. They draw against Totenham, but they were lucky enough in that game. That caused by Tottenham hitting the post three times. They may not be lucky enough when they're facing Atalanta soon.
As for the bet, id' prefer to pick Atalanta win (2.27). It offers better chance to win instead of total over 2.5, which offers less. Atalanta is also having greater chance to win. It means the possibility to doubled our money is there.
Yes, Roma looks like trash, on average 1 point per 1 game is the pace of the prodigals which dream of avoiding relegation.
In fact, it is unclear why bookmakers are so generous in their assessment of the odds for Atalanta to win - if you look at it on paper, Atalanta has no less than a 50% chance of winning. All the statistics say so. Is the Ranieri factor really that strong? Either the bookmakers know something or the money flow is like that, although who in their right mind would bet on Roma after Mourinho left?
