Kieft spent four years in Italy during his playing career and is delighted by Juve's show of ambition.
Kieft added: "The big question remains: 'What can Ronaldo do?' And: 'Can he still do it?' In the spring Ronaldo still convinced for the Juve-Real in the Champions League match with that great overhead kick. And he is ambitious. I would find it a spectacular transfer, which I would like to see take place."
