Juventus players are happy being involved with Italy this week.
Many sides, including Juventus, Milan and Inter, have complained that their players risk injury during the two upcoming friendlies against Poland and Uruguay.
"The clubs should always collaborate with the Nazionale, which is something unique and wonderful, not to mention very important," said Juve midfielder Pirlo.
His Bianconeri and Italy teammate Buffon agreed that players must not be asked to choose between club and country.
"All of us come to the Nazionale with joy. I understand our Coaches might be disappointed at having to interrupt their work, but in his playing career Antonio Conte would rush to go on international duty."
