Mason Greenwood is becoming increasingly frustrated with Cristiano Ronaldo's influence at Manchester United as he continues to be left on the bench by Ralf Rangnick, according to a report.
The 20-year-old was an important figure under Ole Gunnar Solskjaer before the Norwegian was sacked, but has dropped down the pecking order with Rangnick now at the helm.
Greenwood scored an acrobatic goal in Man United's 1-1 draw against Young Boys but he remains on the fringes of the German's side in the Premier League.
And El Nacional claims that he is 'upset' with his lack of playing time and the fact Ronaldo is always the first name on the teamsheet.

The report also says Greenwood is not happy with the way the five-time Ballon d'Or winner has assumed control of the Man Utd dressing room in such a short space of time.
It's claimed Greenwood is also looking into the possibility of leaving Old Trafford, as a result, as he is well aware of the serious attention he would attract from suitors.
Arsenal, Juventus and Barcelona are the teams credited with interest.
This isn't the first time there has been alleged friction between Greenwood and Ronaldo either.
The Portugal star questioned United's younger players ahead of their 5-0 drubbing against Liverpool at Old Trafford, suggesting there is some unrest within the dressing room, particularly among the senior players.
As quoted by DAZN via The Telegraph, Ronaldo said: “I don’t mean only in football, this new generation since probably 1995 they are thinking different.
"The life, the football, the struggles, this has to come from inside of you. You have to accept some times that you don’t agree with."
Several members of United's squad were born after 1995, including Marcus Rashford, Amad Diallo, Diogo Dalot, Jadon Sancho, Aaron Wan-Bissaka, Dean Henderson, Donny van de Beek and Greenwood.
The experienced forward is also believed to be annoyed at Greenwood's tendency to shoot rather than supplying him with a scoring opportunity when they have been paired together this season.
Their lack of synergy was apparent in United's embarrassing 2-0 defeat in the Manchester derby and they mustered just one shot on target against Pep Guardiola's men
Greenwood's role has diminished since Rangnick has arrived at the club, but the 63-year-old was full of praise for the "massive talent" following United's victory over Young Boys and reckons he can become a regular in his side if keeps developing.
He said: "I think today he also showed not only the quality because of that beautiful goal, but also the way that he set up the opportunity for Juan Mata was brilliant.
"He's a massive talent - left foot, right foot, good on the ball. Also the way that he set up the goal for Fred on Sunday, so it's about continuity.
"He has to develop physically but technically for his age he is a great player. My job is to develop him, to make an athlete out of him and if he manages to do that, he can become a regular player for this club."
