Manchester United boss Ole Gunnar Solskjaer has dismissed Sir Alex Ferguson's criticism of his decision to leave Cristiano Ronaldo out of the home draw with Everton on 2 October.
Ferguson told UFC legend Khabib Nurmagomedov that managers should always play their strongest team in a video which was uploaded onto social media.
"I'm quite relaxed about it," said Solskjaer. "It's not really fair on the gaffer that something like this gets broadcast. You always have opinions and you speak to people in confidence.
"I told my wife quite a few times that I disagreed with him but that never made headlines as a player.
"I'm sure Sir Alex knows that it doesn't bother me. We all want to see Cristiano because he's unique.
"But the plain fact of it is he cannot play every single game. That's just physical nature and human nature."
