It actually appear like a bad decision when Roma sacked Jose Mourinho but if you look at it carefully, you will realise that the management's were looking at the results. Football is not based of past glories, it is business that present results is very vital for decision making. Just unfortunate that despite sacking Mourinho, the situation did not change much. Now that it is looking like they might not scale through to the championship spot, they can just concentrate in getting a spot at the Europa. Their one zero win against Lazio is actually a good one.
Many of us criticized the Roma management for sacking an experienced coach like Mourinho. Because Mourinho was a very experienced coach. Even so, Roma management took the tough decision to sack such an experienced coach. And now it seems Roma's decision was right.

De Rossi is not experienced. But he correctly understood the internal problems of the Roma team. And now Roma's performance is very good. Roma played a total of 15 matches after De Rossi took over as coach. Roma have won 10 matches in Bebon and lost only 2 matches. De Rossi has been successful with Roma so far. Roma players have been consistently performing well. And now Roma are fighting for the top four of the table. Roma is only 2 points behind Bologna. If Bologna's performance is not consistent, we will probably see Roma in fourth place in the table.
