Former Manchester United boss Jose Mourinho had a dig at 'soft' present day players in an interview with Bein Sport.
He suggested players who are given an easy route to the top are often more sensitive to criticism.
Mourinho said: "There are players that were brought in in a different way, where possibly they have an easier social life.
"Probably they had an easier coming to the top level of football. Everything comes too easy to them.
"Some of them they don't react in the same way.
"Certain moments and certain decorations, and strong public words, some of them have some risk."
