Graeme Souness has expressed his concern for one Manchester United star but also blasted two of his team-mates.
The Mail Sport columnist, appearing on talkSPORT argued that players at Old Trafford 'get too much too soon'.
Erik ten Hag's side have endured a frustrating season as they lie seventh in the Premier League standings, and only barely reached the FA Cup final on penalties, after throwing away a 3-0 lead against Championship side Coventry City.
Alejando Garnacho has been one of Manchester United's bright sparks of the season, but Souness highlighted his concerns for the teenage Argentine forward.
He told talkSPORT: 'Garnacho for me is an exceptionally talented young man but I worry for him.
Graeme Souness expressed concern for one Manchester United and ripped into two others
Souness, speaking on talkSPORT, said Manchester United players 'get too much too soon'
Souness said he is worried for promising youngster Alejandro Garnacho over the attention United players receive
'It's just an observation, called me old-fashioned, call me a dinosaur, but he's got two ear-rings in the warm-up, on the pitch.
'He's a young boy just learning the game. Coming back to the point that Joe Cole would have made about good senior pros, pointing out to younger guys how you live your life, how you act, how you train, your attitude to life.
'And I just worry, it's an age old thing, it's not a new thing at Manchester United, they have always been the most glamorous football club in this country and just like Bayern Munich in Germany are called FC Hollywood, I think you can use the same term to talk about Manchester United.
'They get too much too soon at Manchester United, that's my take on it.'
Explaining his point he went on to say that team-mate Marcus Rashford was an example of this, and claimed that his ability appears to be declining at the age of 26.
He said: 'When we were the dominant team at Liverpool they (United) were the bigger stars than we were. They get so much attention Manchester United players and I think it's to their detriment.
'Especially the modern game when the kind of rewards these boys get, they get far too much far too soon and I think Rashford is a case in point.
'He's 26, should just be now approaching his best years but it looks like his best years are long gone.'
Souness said Rashford was an example of players getting 'too much too soon' and said that while he should be approaching his prime, he appears to be past his best years
Souness also ripped into Antony for cupping his ears towards Coventry players after their FA Cup semi-final shootout win, commenting that United 'didn't knock out Real Madrid'
Souness said Antony's act didn't resemble the 'class' expected from Manchester United
The former Liverpool and Scotland midfielder also reserved criticism for Antony, after the £85m signing cupped his ears towards Coventry players after their FA Cup semi-final penalty shootout victory.
When asked what his thoughts on the Brazilian's actions were, he responded: 'Naff.
'Man United are a class act. But for a player to act like that it's naff, it's like you just don't do that as a Man United player.
'It wasn't Real Madrid you've just knocked out. It was Coventry, a team from the Championship.
Manchester United have endured a frustrating season and are seventh in the standings
Manchester City are standing in the way of Erik ten Hag and achieving a cup trophy this season
'It's not the first time I've seen it from him, doing daft stuff. All the daft stuff about Rashford not closing down properly, about antics on match-day, that's all ironed out on the training ground. You get after them on the training ground and as a manager you encourage the senior players to get after them in the training ground.'
After beating Coventry, Manchester United will face local rivals Man City in a rematch from last year's FA Cup final.
The Red Devils appear to be all but out of the Champions League race and are instead fighting for a Europa League spot.
