Juventus are making a big Bosman push for Chelsea defender Toni Rudiger.

The Sun says Juve have offered the German centre-back a four-year deal worth £22.5 million, and they now want to make him the centre-piece of a rebuilt defence.

Juve believe that by giving the 29-year-old top billing in Turin, it will hep lure him away from rivals, who are also chasing the German's signature when his contract expires in the summer.

Club legend Giorgio Chiellini, 37, has spent 18 years at Juventus, playing more than 400 top-flight league games and winning nine Serie A titles.

But despite his longevity, he remains the heartbeat of the back line, and Juve bosses want him to mentor Rudiger for one year, before he finally hangs up his boots.

Rudiger is set to be out of contract at the end of the season and the Blues cannot offer him an extension because of UK government sanctions placed on club owner Roman Abramovich.
