AC Milan legend Billy Costacurta feels Juventus should sign Cagliari midfielder Radja Nainggolan.

The Old Lady are expected to bring in a new midfielder before the end of this month and the Belgian is being strongly linked, as is Valon Behrami of Fiorentina.

"I'd go for the younger player, therefore the Belgian," Costacurta told Sky Sport Italia. "I fell in love with him as a footballer when he was at Piacenza.

"Behrami is not a bad player, but Nainggolan has something extra.

"Juve director general Beppe Marotta would have done some extraordinary work if he adds the Cagliari midfielder to Marco Borriello and Martin Caceres.

"They are all players who can start in the first team or accept the bench."
