Cristiano Ronaldo, a forward for Manchester United (MAN UTD), has said that he has had disagreements with several of his teammates because they are unable to take criticism.

Since Ralf Rangnick took over as temporary manager, there have been reports of in-fighting in the dressing room.

One of the main issues Ronaldo, Rangnick, and the other older players in the dressing room are dealing with is the younger players’ refusal to listen to their counsel.

During his initial tenure at Old Trafford, the 36-year-old stated that he was receptive to advice from the club’s more experienced players.

“The mature players, the older players, can always help the younger players,” Ronaldo told Sky Sports.

“But I can give you an example if I give you advice, even if you are younger than me, but if that’s not in your plan during your daily life then it will be difficult. You can speak all day with that person, but if it’s not coming from inside of you then it is impossible.

“I can remember when I was 18, 19, 20, some older players spoke to me but I put that as ‘Cristiano, you have to improve, they know more than you, they are more experienced than you, they passed through many bad moments’.

“But the other people do not accept when you criticise them – I don’t say this in relation to our players but in general, I have kids, I know. Sometimes if you become a little bit harder they do the opposite. You have to find the right balance to speak with them.

“But in my opinion, the main point is, it should come from inside you. You should be proud of yourself and look in the mirror and say ‘Listen, I gave everything and I think all of us should do that because new year, we change the page and we have many things to win.

“We have to believe in that, if not, it will be a nightmare.”
