Rooney saw Rashford break into the United team during his latter years at Old Trafford and believes his former teammate has 'a bright future'.
“He has got a bit of everything," England's record goal scorer told talkSPORT. "He is quick, he is strong. The only thing he could probably work on is his heading.
“He is fantastic. He has got so much ability and it is great to see him doing so well.
"For Manchester United and England, he has certainly got a bright future."
