Manchester United sent scouts to Stadio Artemio Franchi on Sunday to watch Juan Cuadrado, reports suggest.
The Colombian scored one of the goals as Fiorentina beat Udinese 2-1 yesterday to maintain their challenge for third place.
And La Nazione claim that scouts from the Premier League champions were present, as they look to overhaul their squad in the summer.
The Old Trafford outfit have been linked with a number of top European stars for next term, with Cuadrado the latest name on that list.
David Moyes’ men will face stiff competition should they want to bring in the winger though.
As he is currently co-owned by Udinese and the Viola, the Tuscan outfit are believed to want to permanently sign the South American during the off-season.
But Arsenal and Bayern Munich have also been rumoured to be keeping an eye on the former Lecce man.
