Fortune, however, does not want his former club to sell their key players, especially a talent like Mainoo.
He told Boyle Sports, who offer the latest Champions League odds: "I pray to God that Kobbie Mainoo doesn’t leave, look what we saw with Scott McTominay, I’m still scratching my head over how that was allowed to happen. “A homegrown player who had a history with the club, it’s the same with Mainoo, there are links but he can’t be let go, he is a wonderful player. When he came on the scene, I was really surprised by his maturity and the way he played. He is such a talented player but level-headed and down-to-earth. That's what you want as a Manchester United player. I really hope they don't let this one slip.
"They've let McTominay go, which I thought was absolutely crazy because he can play in several positions, he’s a die-hard United fan and came through the academy ranks to get to the first team. “I hope the same mistake isn’t made with Mainoo, he has shown that he is an amazing player and young players do go through periods of poor form or injury but all that talent is there, we know what he is capable of."
