If indeed Roma's performance is getting worse then he must be prepared to be blamed because his performance cannot bring Roma to a better direction but if his condition is stagnant or even better it clearly must remain appreciated because Management's decision to bring De Rosi is the right decision.
From all indications, De Rossi's performance in As Roma as the coach is amazing because all the games that he coached were all won, but some are still saying that all those teams are not strong enough. Yes, I admit that, but seeing this performance, we should have a positive view of De Rossi that shows that he will definitely improve As Roma’s performance.
Of course, in football the result is everything. However, Roma didn't play a very good game against Salernitana. In the first half they had almost no scoring chances and Salernitana attacked very effectively. Candreva, Salernitana's experienced player, performed very well and created important opportunities for Salernitana in the first half. If Roma hadn't taken the lead with a penalty goal in the second half we could have been talking about different things today. De Rossi has a very difficult job at Roma.
