Rashford, 21, is reportedly being targeted by Spanish giants Real Madrid.
“There are some players out there who are happy to train and not play on a Saturday, but I don’t think he’s one of those types of players,” Ince told Paddy Power.
“If he doesn’t want to move permanently, he should be considering a loan move to another English club. Because he should be playing every week. He shouldn’t be a bit part player.”
Ince added: “He’s naive at times, but he’s got bags of talent and he’s still young,” Ince said of the United starlet.
“He always looks fantastic for England, too. His main issue is that at the minute it’s not clear what his best position is.
“He’s at the age now where he needs to decide whether he wants to play every so often for United, or all the time for another club.
“A part of me wonders whether he sees young players like Jadon Sancho, flying at Borussia Dortmund and playing every week, and feels a bit jealous.”
