Rashford's attendance at an NBA game in New York during the last international break - after he'd been left out of the England squad again - raised eyebrows and reignited debates about his priorities.
Speaking to Casino Utan Spelpaus, Saha suggested that such distractions hinder his potential: "Marcus has to actually show his obsession about football again. He needs to clearly show that he's obsessed and that he wants to be the best player. If he's doing something outside the game, he will understand the consequences.
"You can do whatever you want, travel everywhere you want, but there are consequences. If you are obsessed, you don’t need those distractions. He should be obsessed, which will only improve his game. When you see interviews with athletes that he really admires, they all say the same thing. When they want to reach the top, they train more than anybody. You don't see them doing anything outside."
