José Mourinho really supports the team he supports, so when Roma managed to score a goal, José Mourinho immediately used a very strong defensive strategy that made it difficult for Torino to reply to the goals that had been won by Roma. To survive in the top three at the top of the standings, Roma still has to keep fighting to secure their position because, in the future, the opponents that it will face will be difficult to beat.
I don't think there's anything new about changing the style of play to be more defensive when the team is already ahead with a quick goal. Because this method is also often used by Mourinho, but AS Roma's luck in this match is because Torino does not have good ability to score goals. So that the defensive strategy implemented by AS Roma in this match can work well.
Because sometimes, when Mourinho implements a strategy like this, the result is that Mourinho sometimes gets blunders from this method. Because if the opponent is a top team, then it is very possible for that team to make good use of it successfully to score a goal back. But yes, congrats to AS Roma, because it looks like at this moment AS Roma has a good chance to finish in the top four, considering that Inter continues to get bad results.
