Juventus have joined Southampton, Roma and Lazio in chasing Aston Villa defender Ron Vlaar.
The 29-year-old’s future in Birmingham remains in doubt, as he has one year left on his contract with Villa.
He already worked with Southampton manager Ronald Koeman at Feyenoord, so they are seen as the favourites.
Lazio have been linked with Vlaar for some time and Roma consider him a suitable alternative if Mehdi Benatia is sold to Manchester United or Chelsea.
According to the Daily Mail, Juventus are also joining the hunt for Dutch centre-back Vlaar this summer.
