Juventus officials were at the Emirates Stadium on Wednesday to watch Borussia Dortmund stopper Mats Hummels.
The Old Lady’s sporting director, Fabio Paratici, was reportedly in London to see the stopper in Champions League action against Arsenal.
Hummels, 22, is an imposing German international who has a transfer market value of around €15m.
Juve director general Beppe Marotta admitted this week that the club would look to strengthen the squad after Christmas, although he insisted they would only make low-key signings.
The Bianconeri are expected to make use of the New Year window by bringing in a new-centre back given their restricted options in that role.
Borussia lost 2-1 to Arsenal last night, a result which leaves them at the bottom of Group F with one game to go.
