Manchester United have not abandoned all hope of signing Frenkie de Jong despite their failed pursuit of the Dutch midfielder in the summer.
De Jong, 25, whose contract at the Nou Camp was complicated by the club's financial restructuring, never gave any indication he was willing to leave.
But it is understood Ten Hag wants to revisit the situation in the summer.
After missing out on De Jong, United instead bolstered their midfield by signing Brazilian Casemiro from Real Madrid for £70m and Christian Eriksen, who has proved to be an astute free transfer arrival from Brentford.
