Blind has been put up for sale by United today.
And father Danny, the former Holland coach, revealed: "I can confirm that Roma wants him, but Manchester United does not want him to go on a loan basis, only on a definitive basis. They do not want to sell him, only in the summer.
"The price is good, but a deal is going to be difficult.
"It will be very difficult, because Manchester United wants to use him in the Champions League, Premier League and FA Cup. Italy would be an interesting step for him, but Manchester United is a huge club that does not necessarily have to sell because they do not need the money. José Mourinho wants to keep the group together, so it's very difficult."
