AS Roma won and it has push to them to 4th position on the table. They're aiming higher spots. José Mourinho intends to make his team very strong and competitive, absolutely no time for the Portuguese man to relent, he's desperate to achieving good results. There's no way AS Roma would have become victorious against the home side if Sassuolo wasn't issued a red card, that alone ruined things for the club. Sassuolo was opportune to win the game but the red card issued out to Daniel Boloca by the referree Marcenaro Matteo.
AS Roma was lucky because their opponent during the match received a red card in the 63rd minute. So AS Roma took advantage of this moment to corner Sassuolo's defense and win easily. If Sassuolo didn't get a red card, then AS Roma's chances of winning were very small. The difference in points between the third and first positions is quite far away, and AS Roma must keep trying hard to win the third position.
The red card received by the Sassuolo player changed everything, I don't mean to blame him, but it is undeniable that one of the reasons why in the end AS Roma could win this match was because they were superior in number of players in the second half precisely in the 63rd minute. The 2 goals they scored came after Sassuolo got the red card.
Apart from all that, AS Roma successfully utilized the advantage of the number of players, so they could ensure victory in this match.
You are right about betting on these teams and the bets seem safe to me to bet in Inter Mian and Juvenyos is these two games but the fact about betting is you should sometimes accept more risk to win more reward. In fact, you should consider a chance for yourself if the bets are not right and for example, Udinese beats Inter Milan however the possibility is not high but the rates are very good.

We choose the league that we're acquainted with and place wagers on matches that we're also confident about and not rushing to place bets with the public. We ought to apply wisdom whenever we're betting in the system, not just implement wager on matches simply because our favorite clubs have fixtures, we should only bet on our clubs when we know fully that our clubs will thrash the next oppositions without challenges. Any side that encounter Inter Milan currently, their chances of losing will stake high because Inter Milan are first on the table and Simeone Inzaghi wouldn't keen on compromising his chances.
Yes we have to be realistic in this, I mean we can't possibly bet on a team that is at the bottom of the table with an opponent that is at the top of the table. At first glance we would know who would win the match if it was a match between two very different teams. Likewise with the team that is our favorite for example, even though it is a favorite but still we have to think realistically in this case, because we are betting money. So if that's the case, then I would bet on the strongest team, no matter who they are.
