Manchester United are believed to be monitoring Morocco international Sofyan Amrabat, according to reports.
Mail Sport previously reported that the club were set to rekindle their interest in the midfielder, after initially targeting him during the January window.
Instead, Erik ten Hag's side made a move for Marcel Sabitzer to bolster their midfield following an injury to Christian Eriksen.
Fiorentina were previously unwilling to part with the 26-year-old, who has become a bedrock in Vincenzo Italiano's high-achieving side, this season helping them reach the finals of the Coppa Italia and the Europa Conference League.
