Cristiano Ronaldo and Manchester United interim boss Ralf Rangnick's relationship is completely fractured as the forward believes the manager is out of his depth, according to reports.
The German was brought in to turn the Red Devils' season around following the dismissal of Ole Gunnar Solskjaer.
But United have endured another series of disappointing results to sit sixth in the Premier League and tensions are said to be building in the dressing room.
Rangnick does not have the support of the squad's 'leading heavyweights', notably the Portugal international, according to Spanish outlet AS.
The relationship between the player and manager is now said to be completely fractured.
The five-time Ballon d'Or winner believes Rangnick does not have the ability to manage United and is out of his depth at Old Trafford.
To make matters worse, Rangnick is said to have angered Ronaldo further last Friday, after he accused the forward of not performing in front of goal.
Ronaldo is the club's top scorer this season but has failed to register a goal in the last five league games and Rangnick appears to be unhappy with the performance.
The 37-year-old has not hesitated to show his frustrations this season either, with his most recent outburst coming against Burnley last week.
Rangnick dropped Ronaldo to the bench in favour of Edinson Cavani midweek but the Portugal international was brought on as a second-half substitute at Turf Moor.
The forward made little impression after replacing Cavani in the 66th minute and after United only managed to scrape a point against rock-bottom Burnley he stormed straight down the tunnel.
Other attempts from elsewhere in the dressing room have been made to undermine Rangnick and his coaching staff.
And last week, it was claimed that some United players refer to Rangnick's No 2, Chris Armas, as Ted Lasso - the hapless coach in an Apple+ TV series.
However, despite a tempestuous relationship with the manager, Ronaldo is said to be happy living with his family in Manchester and reportedly has no plans to move.
Rangnick will be vacating his position in May and Ronaldo could be happy to stay at Old Trafford with the 63-year-old no longer at the helm.
However, United's board have yet to appoint a permanent manager for when the interim boss leaves at the end of the season.
Sportmail revealed last week that the players would prefer PSG boss Mauricio Pochettino to take charge at Old Trafford, while Rangnick backs Ajax manager Erik ten Hag.
While a cloud of uncertainty lingers over Old Trafford, there is one thing that seemingly is not in doubt - United's players will be looking forward to welcoming a new manager in summer.
