Ornstein was asked to speak about the likelihood of United star Marcus Rashford leaving the club, before issuing an update on Mainoo's contract situation - with his current terms running until 2027.
He said on NBC on Sunday: "If a departure is going to happen [for Rashford], a sale in particular, maybe it’s more likely in the summer, but it would represent pure profit, something we hear about so much, because he was an academy graduate. In the same way that Kobbie Mainoo might be, he’s out of contract in 2027 – no news on a new deal. Alejandro Garnacho too, I don’t think anybody in that bracket is off the table."
