We travel to Brentford for the big kick-off in the Premier League on Saturday (5.30pm).
Asked in his pre-Brentford press conference about his summer and how happy he was on the eve of the Premier League season, Roberto responded: "It seems I'm here for 10 years now! Three months, just three months, a very intense three months.
"I think we can't forget what happened last season. It's a lesson, a big lesson for us, for every one of us. Anyway, we have to go to another page and to start another season, an important season.
"We are building, I think, a new project and now the big challenge, without talking too much about the target, the goal of this season... the first two targets we have very clear in ourselves is to find the soul of the team, the first target and the second target, to improve in our organisation of football, with the ball, without the ball.
"Our style has to be the key of our season, like our soul. These two characteristics I want to find as soon as possible."
Speaking later in the conference, Roberto added: "I think if I spoke at the beginning of my press conference about the soul - to find the soul, every one of us, they have to stay here with the right spirit, proud to stay here, and with great ambition, great motivation, otherwise it's tough, one season with me, without motivation, without ambition, it becomes tough for everyone."
