Former Manchester United striker Brian McClair has urged manager Jose Mourinho to smile more and appear as if he is "enjoying one of the best jobs in world football".
The Portuguese has voiced several frustrations during pre-season including the absence of players, the club's lack of new signings and the poor showing in the 4-1 loss to rivals Liverpool.
Mourinho also stated that he would not have paid to watch United's friendly matches in the United States were he a Red Devils fan.
"There has to be a balance," McClair told BBC Sport. "You should, at some point, look as though you are enjoying it. It is fine to be critical, upset and happy - Sir Alex [Ferguson] had those moments too, but there were several times where he looked very happy.
"Jose maybe enjoys himself internally but from a football point of view, the Manchester United fans would very much welcome seeing him smiling and laughing at appropriate times.
"From an opposite view, your great rivals have been Liverpool and they have a coach [Jurgen Klopp] who does laugh and smile and look pleased to be there. That must grate as well at times, if you are a United fan."
United begin their Premier League campaign against former champions Leicester City next Friday.
