Rio Ferdinand says he feels "worried" about Manchester United striker Marcus Rashford and has questioned "what is going on behind the scenes".
Rashford, 24, was one of six changes for United on Saturday as they suffered a damaging 1-0 defeat to Everton at Goodison Park.
The England international had a few bright moments early in the match but then faded, as a deflected strike from Anthony Gordon secured a vital win for Everton in their battle against relegation.
Rashford was substituted shortly after the hour mark, with Anthony Elanga brought on as his replacement.
He has now gone eight Premier League games in a row without scoring and has managed just five goals in all competitions this season.
Former United defender Ferdinand is concerned about Rashford and believes the striker is being affected more than most by the current uncertainty surrounding Old Trafford.
"He's left me worried and I'm asking a lot of questions about what is going on behind the scenes," Ferdinand told BT Sport.
"Slumped shoulders, not as confident.
"I think it stems from the uncertainty of the football club. He's a local boy, who is desperate for this football club to do well.
"He grew up on success, it's all he saw. It's deception as a football player that you hide what you're really feeling.
"I don't think he can hide it through his body language. He wants some success back at the club."
United goalkeeper David De Gea was critical of his side's performance, describing it as a "disgrace" in his post-match interview.
"They played Wednesday and they were tired but they had more desire than us, that is not acceptable," he said.
"Very sad to lose. It is a disgrace from us. We should be winning this game."
United could end the weekend six points adrift of the Champions League places if fourth-place Tottenham beat Aston Villa on Saturday night.
