Midfielder Paul Pogba reveals the work ethic at Juventus "made me feel like Manchester United was a vacation".
The France international spoke about his different football experiences in his country, England and Italy.
"People ought to know that it is not easy at Juve," Pogba was quoted as saying by football-italia.net on Saturday.
"There is a culture of work that is different to anything else abroad. I was at Manchester United and I can tell you it made me feel like being on vacation in comparison to Juve," the 22-year-old added.
Pogba, who joined Juventus in 2012 from United, said that four consecutive Seria A titles are a reflection of how the Turin-based players work hard.
"We work so hard here, because all the Scudetti were down to hard work," he reflected.
Juventus midfielder Paul Pogba has described his time at Manchester United as like being on holiday when compared to the work he does at the Italian club.
The France international left Old Trafford four years ago after making just three senior appearances and becoming frustrated at the lack of first-team opportunities handed to him by then-manager Sir Alex Ferguson.
Since joining the Bianconieri as a free agent, Pogba has gone on to become one of the sought-after players in world football. In an interview with Italian newspaper La Stampa, he has claimed that the club’s intensity and emphasis on hard work is one of the major reasons behind his improvement.

"People need to know that nothing at Juve is easy," he said. "There is a different culture of work compared to elsewhere. I was at Manchester and it seemed like being on holiday.
"Here we work so much. All these titles, we didn't steal them. It was by working right to the end."
The 22-year-old, who has regularly been linked with a move to Manchester City and Barcelona among other elite clubs, revealed that he enjoys playing as some of his suitors on the Fifa video game series.
"I pick Juve, Barca, Madrid and City," he said. "I even play by myself and sometimes get annoyed because the Pogba in the video game plays better than me."
Pogba also cited City midfielder Yaya Toure, as well as Barca’s Andres Iniesta and Bayern Munich’s Arturo Vidal, as key influences and the midfielders he watches in order to improve his game.
