Every manager has difference strategies, under Daniele De Rossi make difference game play with AS Roma more active for offensive than Jose Mourinho era prefer for full defensive.
Indeed, we know that the strategy adopted by Mourinho is more defensive, especially if the opponent they are facing is much stronger, they will defend completely and only rely on counter attacks. Meanwhile, in the De Rossi era, AS Roma were more daring in attacking and the results were quite satisfying because there were good changes that they could show.
With a more open strategy like that, it is possible that they will have a greater chance of winning the match, and De Rossi dared to do that. What De Rossi has shown with AS Roma currently looks good and hopefully they can maintain it, because it is not easy to change the style of play, it requires a process.
