Inter Milan coach Simone Inzaghi expects his title winning squad to be improved this summer.
Piotr Zielinski (Napoli) and Mehdi Taremi (Porto) have already agreed Bosman deals.
Inzaghi said: "I am lucky enough to have a club that is always present and active, I think of Marotta, Ausilio, Baccin, our president who unfortunately is not here with us. We are always on the move, in football there is always room for improvement year after year.
"We are already doing something. Since my arrival, we have goals and budget, the managers are very good and are trying to go further to create a competitive team because we have a fan base that deserves to always remain at the top.
"It will be a new season for everyone, at the end of the championship we usually go on holiday to plan the new season and instead there is the Club World Cup, it will be a new thing for we coaches but together with the club we are already thinking about making sure we are ready when the Club World Cup arrives."
