Zlatan Ibrahimovic, who is known for not mincing his words, has now hit out at Cristiano Ronaldo, calling one of his statements "bulls***".
The 38-year-old, who is said to be close to a return to Italy's Serie A, recently gave an exclusive interview to GQ Italia.
Among many topics discussed was Ronaldo's statement that he joined Juventus because he wanted a new "challenge".
Ibrahimovic, though, has insisted that playing for the record Serie A champions cannot be considered a tough choice.
"Going to Juventus was a challenge for him? A challenge? Seriously? A challenge going to a club coming from seven league titles in a row?! Bullshit," he said.

The Swede, whose contract with LA Galaxy expires at the end of the year, also confirmed that he will be returning to Italy, but did not give away which club he will join.
"I go to a team that has to win again, that has to renew its history, which is looking for a challenge against everyone," he added.
"Only then will I be able to find the necessary stimuli to surprise you again."
Ibrahimovic will be a free agent at the end of the month but is expected to return to AC Milan, having already played for the Rossoneri between 2010 and 2012.
