Roma tasted a first league defeat against Hellas Verona last weekend.
The Giallorossi are hoping to return to winning ways in their next Serie A game.
Inspiring his side to get back to business, Mourinho says the Stadio Olimpico outfit must turn sadness into motivation.
“We lost a game, we didn’t play well. We analyzed the game in detail with the players, looking to the future and not the match, which we can no longer win. We lost three points,” he said.
“We have lost, we are sad, but we must remain balanced. It is not a result that pushes me one way or the other. We still have a lot of work to do, but we must remain calm on the positive and the negative.
“We are not candidates for anything, just to win the next game. We need to turn sadness into motivation, not sorrow into depression. And we lost only one, what should those who lost two or three do? We make our way quiet but with ambition.
“It’s not a problem to lose a game because of too much ambition or desire. With the changes I made, I knew we could win or lose.
“The problem is the three goals. Those are too many. And from a defensive point of view, we had some issues with Verona.
“I can’t control the players, I can’t control anyone, nor the fans. I can only try to influence those who are close to me, namely the players. I liked the locker room after the wins. I saw a balanced locker room and, after the defeat with Verona, I saw them sad, but always with balance.
“I repeat: it is necessary to transform sadness into motivation, but always with this level of stability.
“The season is not a highway, it is full of curves. Maybe it’s a highway for teams like PSG and Bayern that win every game. Don’t worry, let’s go slowly.”
