Former Liverpool forward John Toshack, says the chance to play alongside the five-time Ballon d’Or winner is too much to turn down.
Cristiano Ronaldo left Real Madrid to join Juventus last summer after winning four Champions League titles in the last five years.
And he has gone from strength to strength since moving to Turin, helping Juventus to the top of Serie A.
Wales international Ramsey has been free to talk to foreign clubs over a move since January 1 and Juventus have been strongly linked.

Ramsey can leave the Gunners as a free agent in the summer after his contract was not renewed at the Emirates.
And Toshack believes choosing Juventus over all other clubs linked should be priority for Ramsey.
“He has a unique opportunity to play with Cristiano Ronaldo, to grow, to improve, and that’s a lucky break for a lad who hasn’t had much luck,” he told La Gazetta dello Sport.
“I remember watching TV when he really hurt himself playing against Stoke in 2010. I was stunned.
“It took him nine months to get back, but the experience helped forge his character.
Aaron Ramsey is free to discuss a deal with foreign clubs .
“He grew up over time, but now he’s 28 years old and read to explode. Juventus are doing really well when it comes to free agents and contracts running down, picking up top players for free like Emre Can and Sami Khedira. They’ve already got a great talent like Miralem Pjanic and World Cup winner Blaise Matuidi, so it’s an excellent midfield.
“I would recommend to everyone, football players or not, to go abroad.
“I’ve made it a point of my management career to go out and get to know new cultures. I can assure you that for British players, it’s not easy to move abroad.
“It’s crucial that Aaron doesn’t make the same mistake that Bale did at Madrid.
“He needs to learn the local language straight away. That might also be why it’s best he join Juve in the summer and not in January.”
Toshack does think, though, that Ramsey still has much to learn.
He added of the Arsenal star: “He was always a talent, but I don’t know if I’d call him a star yet.
“For the moment he is playing for a big club and very soon he’ll be at a huge club.
