Ten Hag stated: "It will be either one or the other. Both of them do not seem realistic."
The coach admits he'd welcome the arrival of Blind.
"A player with a lot of experience, in the Premier League and in the Dutch national team. Building very well and organisationally very strong. Moreover, he is a stable personality. Just like the arrival of Dusan Tadic, this also counts as a considerable effort of the club.
"We'll do everything, but also depend on other parties.
"He can handle both positions well, both as a central defender and as a controlling midfielder. But what his position will be depends on how others develop."
