Speaking after England's win over Bulgaria, Keane was discussing Rashford's inconsistent form, and suggested he could do worse than copy Sterling to improve his game.
“We said before the game he's [Sterling] affecting games over the last couple of years," Keane explained.
“We spoke about Rashford, Rashford, sometimes the best example for any player is one of their team-mates.
“Rashford can learn so much from Sterling, whether training with him or watching him at close quarters.
“That's a great lesson and hopefully he is picking up them tips that we did see in the second half."
