In my opinion Sociedad have bigger chances to avoid loss than bookies wants to suggest for us in their odds.

I'm not convinced by Roma in last weeks, especially in attack - they have serious problems with creativity and finishing product. Roma failed to win on away against Lecce (1:1, scored from penalty kick). They lost on away against Salzburg 'to nil'. They won at home against Verona, but they had only 0.79 expected goals scored. They lost 1:2 on away against Cremonese (the worst team in whole Serie A). At the weekend they won against Juventus at home, but they recorded only 6 shots and had 0.62 expected goals scored.

On the other hand Sociedad is really hard nut to crack. They didn't lost in 15 of last 19 matches in all competitions. For sure they coming for this game with defensive mindset to avoid loss and I see huge problems for Roma to break their consistency at the back. According to the expected goals conceded model Sociedad have second-best defensive formation in La Liga. So far they conceded 23 goals in 24 league matches, but according to the model they should concede even less (20.6). Sociedad is extremely solid team on the road - they didn't lost in 9 of 13 away league matches.

On those circumstances I expect really hard game for hosts.

在我看来，Sociedad避免输球的几率比博彩公司给我们的指数要大。

我不相信罗马在过去几周的表现，尤其是在进攻端——他们在创造力和射门上存在严重的问题。罗马未能在客场战胜莱切(1:1，点球得分)。他们在客场与萨尔茨堡的比赛中“零比零”失利。他们在主场战胜了维罗纳，但他们的预期进球数只有0.79个。他们在客场1:2输给了克雷莫纳斯(整个意甲最差的球队)，周末在主场战胜尤文图斯，但他们只有6次射门，预期进球数为0.62个。

另一方面，Sociedad真的很难破解。在过去的19场比赛中，他们有15场没有输球。当然，他们带着防守的心态来参加这场比赛，以避免输球，我认为罗马在后防线上的稳定性会被打破。根据预期失球模型，Sociedad拥有西甲第二好的防守阵型。到目前为止，他们在24场联赛中丢了23个球，但根据模型，他们应该丢更少(20.6个)。Sociedad是一支在客场表现非常稳定的球队，他们在13场客场比赛中9场不败。

在这种情况下，我预计东道主的比赛会很艰难。
