Reports in Italy suggest Watford will send scouts to the Derby della Madonnina, to assess Mateo Musacchio and Andrea Ranocchia.
The English club is owned by the Pozzo family, who also own Udinese, and frequently does transfer business in Italy.
According to FCInterNews, the Hornets will send scouts to the Inter-Milan game on October 21 as they look for a centre-back.
The names in the frame appear to be Musacchio of Milan and former Inter captain Ranocchia.
