But despite his last goal coming at the end of October, Barnes has tipped the England international to re-discover his form and become a huge player for the Red Devils.
“Marcus Rashford is the future of Manchester United,” Barnes added.
“Marcus Rashford is the future of Manchester United, along with Greenwood and Jadon Sancho. Rashford should play every week if he’s fit.
“The focus has been [Bruno] Fernandes, [Paul] Pogba and Ronaldo and the team selection has reflected that, even when he’s been fit.
“He’s suffered a bit in confidence but having so much focus on Pogba, Ronaldo and Fernandes has detracted from the younger players which has really worked against them.”
