Inter Milan president Erick Thohir has welcomed Cristiano Ronaldo's arrival at Juventus.

Thohir believes his addition will be good for Serie A.

"I think so," Thohir said.

“In the 90s Serie A was the best league in the world, now it has to compete with other tournaments and the most important league is the Premier League, which competes with La Liga and the Italian league.

“But if there are three clubs who dominate in Spain, in Italy there are six clubs who could compete for the title so it's quite a complicated competition.

“Several of the best players in the world play in England, the absolute best - Cristiano Ronaldo and Lionel Messi - have played in Spain and France has made progress but there's only Paris Saint-Germain.

“What I talked about in 2013 is becoming a reality, Serie A needs new investors. After my arrival, and that of James Pallotta at Roma, there's Suning, Joey Saputo has come to Bologna and now Milan have American owners too.

“The arrival of Cristiano Ronaldo will also benefit Serie A as well as Juventus, especially financially.

“His arrival in Italy is very positive because he'll also help with the money we can make for TV rights and other things."
