Rashford is without a goal in his last 12 appearances for United as Erik ten Hag’s side have endured an inconsistent start to the season.
The England international’s current struggles were summed up in the closing stages of United’s 1-0 win over Luton Town on Saturday as he spurned an excellent one-on-one chance after being played through on goal by Antony.
When asked why Rashford is currently out of form for United, Shearer told Premier League productions: ‘I think the simple answer is we don’t know because we’re not within the football club.
‘But what we’re looking at is someone who clearly looks very unhappy.
‘He looks moody, and when that’s the case you’re never going to perform at your best.
‘Whether he feels he’s better than what’s at Old Trafford at this moment in time, I don’t know. Whether he feels let down by recruitment because he went to another levels in terms of his goals last year. The club haven’t gone to it this season which maybe he wanted or expected to.
‘You’re not seeing a happy footballer, you’re not seeing a happy person at this moment in time in Marcus Rashford. He looks a different player for England than he does for Manchester United.’
Meanwhile, Jermain Defoe also agrees that Rashford looks unhappy at United and believes his late miss victory over Luton Town at Old Trafford highlights the forward’s current situation at Old Trafford.
Asked if he believed United thought Rashford would improve even further this season, Defoe said: ‘Yeah, I think so.
‘And I think you have to, that’s the pressure of a centre forward, you score 30 goals one season, can you score 31 next season? I think that’s the sort of pressure you have to put on yourself, I think you have to be obsessed with scoring goals, it’s a good pressure.
‘Listen, I love Marcus Rashford, as Al [Shearer] said, when he plays for England he seems like a completely different player.
‘When you look at his vibe and his body language, he doesn’t look happy. That can affect your performance.
‘You see the last chance [against Luton] where he takes two touches, you think a confident Marcus Rashford would hit that first time, where all these familiar situations and instincts kick in. He just seems off it at the minute and they just need to get him back to his best.’
