Rashford has experienced a dip in performances for United after missing the start of the season due to shoulder surgery.
He has contributed three goals and one assist in 15 appearances across all competitions so far and has appeared frustrated on the pitch at times.
The 24-year-old has now gone 11 games without a goal and his struggles were summed up in the 1-0 win over Aston Villa in the FA Cup on Monday night.
Rashford was substituted for the eighth time in his last 10 starts after cutting a disconsolate figure on the pitch at Old Trafford.
Shearer was at the match as a BBC pundit and, according to The Sun, later took the opportunity to call the young England striker to offer tips on handling the pressure and to reassure him he will get through his current dry spell.
According to The Athletic, it is not the first time the Premier League’s record goalscorer has called Rashford.
Shearer, alongside Manchester United legends David Beckham and Paul Ince, called the young striker after England’s penalty shoot-out disappointment against Italy in the Euro 2020 final last summer.
There are reportedly more plans in the works for former players to speak with Rashford, who will have an opportunity to bounce back against Villa in the Premier League on Saturday.

“He’s trying hard, he’s in training, he was doing really well in the last couple of days, that’s why he was quite rightly in the starting XI,” Rangnick said of Rashford after Monday’s game.
“I think in the first-half we found him quite often, we also tried to get him into the box, in the second-half that was not often the case and that’s why at the end of the game I decided to make two changes with Anthony Elanga and Jesse Lingard.
“For strikers, it’s important that they score goals on and off, that there are moments of success, of course, it would be good for Marcus if he could score a goal but as long as he is trying, as long as he is training well I don’t see much of a problem.”
