Juventus have reportedly scouted Athletic Bilbao striker Fernando Llorente and Schalke attacker Jefferson Farfan.
The Serie A club's sporting director Fabio Paratici is believed to have been in attendance at the game between the Europa League tie between the two sides on Thursday, according to Tuttosport.
Llorente took the majority of the plaudits from the fixture, scoring twice against Bilbao's German opponents.
However, Bilbao are said to be extremely reluctant to allow the Spanish international to leave in the summer.
Meanwhile, Peruvian frontman Farfan is out of contract with Schalke at the end of the season.
He recently admitted that he is unlikely to extend his deal with the Bundesliga team.
