Juventus coach Massimiliano Allegri has defended their squad overhaul.
Carlos Tevez, Arturo Vidal and Andrea Pirlo all left Juve over the summer.
“It is always difficult to repeat a season like the one we had, so we all decided it was time for a change," Allegri said to UEFA.com.
“In any case, Tevez wanted to go back to Argentina, Vidal wanted to go to Bayern and Pirlo decided to try his luck in the United States.
“Now we have some talented young players, but we need to work and develop, both individually and as a team. Every season, every year is difficult, but the important thing is trying to improve every day."
