Manchester United sent a representative to run the rule over Juventus midfielder Arturo Vidal, during Sunday's 3-0 victory over AS Roma, reports Sport Witness.
The Chile international has been in fine form for Antonio Conte's side this season, and has been heavily linked with a move away from Turin during the January transfer window.
Red Devils boss David Moyes has been credited with an interest in bringing Vidal to Old Trafford this month, and according to Italian publication Tuttosport, sent a scout from the Premier League champions to make a personal check on him.
However, Manchester United have little chance of securing his signature, with the 26-year-old happy in Italy, playing for the reigning Serie 'A' champions, after helping Juventus claim back-to-back titles in the past two seasons.
Vidal would also command a huge transfer fee, particularly after he signed a new long-term contract with the club - which runs until 2017 - at the end of last year.
