Manchester United manager Jose Mourinho refused to agree or disagree with Rio Ferdinand's criticism of Paul Pogba and Jesse Lingard.
Former United centre-back Ferdinand was critical of the midfield duo during the week after Pogba uploaded a video to Instagram showing off a "new celebration".
A six-time Premier League winner at Old Trafford, Ferdinand questioned Pogba and Lingard's social media use with United languishing in sixth position.
Asked about Ferdinand's comments, Mourinho told reporters: "I respect Rio. He was a big guy in my club. He was a legend in my club.
"I am not, so as somebody that is not his level in the club, I don't think I have any legitimacy to comment on Rio.
"I'm not saying to you that I agree or I disagree. I'm not saying that. I'm just saying that in relation to all these people that they are, in the history of Manchester United, much bigger than I am.
"I don't comment to say I agree or disagree."
Mourinho was speaking ahead of United's trip to struggling Premier League champions Leicester City on Sunday.
