The Red Devils boss recently gave the Englishman advice on his career, but that statement did not go down well with the attacker.

Given the current on-the-pitch crisis Man United are currently experiencing, the Red Devils could do without a behind-the-curtains row. Unfortunately, key player Marcus Rashford is reportedly said to be unhappy with manager Ole Gunnar Solskjaer, an issue which might raise a few concerns.

The Englishman recently made his return from injury in the 4-2 loss against Leicester, having missed the start of the season due to an injury he was carrying throughout the 2020/21 campaign and Euro 2020. While the English giants did not end up enjoying that King Power Stadium visit as they suffered their first Premier League defeat of this term, Rashford came out with his head held high, scoring his team's second goal shortly after coming on to hand them hope – albeit one that amounted to nothing – of pulling off a comeback.

Despite enjoying his comeback, not everything is rosy with Marcus at Old Trafford as the Three Lions attacker is said to be unhappy with his manager. His issue with the Norwegian gaffer has little to do with football; instead, the 23-year-old took a disliking with recent comments made by Ole Gunnar Solskjaer in regards to his activism.

The Man United man has become one of football's biggest role models, as his campaign to tackle child hunger in the United Kingdom has garnered worldwide praise and applause. However, the Englishman has faced criticism, with those angered by his campaign telling him to stick to football.

Here is where Solskjaer's comments come into play. When speaking to the media, the Theatre of Dreams boss offered his player a piece of advice. Unfortunately, it caused a bit of a stir.

"He is coming into the best age for a footballer and he's got a challenge on his hands here at Manchester United – and has a challenge on his hands to play for England," Ole said.

"Marcus has done some remarkable and fantastic things, but now he maybe needs to prioritise his football."

According to David Ornstein of the Athletic, one of England's most reputable journalists, Rashford was left unhappy by the gaffer's choice of words. There is an acceptance in the player's camp that Ole meant no harm, meaning there is no reason to sound the alarm bells as of now. However, given that the club are already struggling with results, Solskjaer will need to bury this issue under the bridge quickly.

The Red Devils are gearing up for a tricky fixtures list, with the Premier League giants set to face Atalanta this midweek in the UEFA Champions League before hosting Liverpool in the English top-flight next weekend.  After that, league clashes with Tottenham, Man City, Chelsea, and Arsenal will come in quick succession, meaning the manager will need to find a solution for their lackluster form before things go from bad to worse.
