Lionel Messi will unveil a 21-metre (70-foot) statue of himself in India on Saturday as he embarks on a three-day tour of the country that has sparked a fan frenzy.

Axar.az informs, citing France 24, the iron sculpture in Kolkata, which shows Messi holding aloft the World Cup, is part of a so-called GOAT Tour that will take in four Indian cities and a possible meeting with Prime Minister Narendra Modi.

The 38-year-old Argentina and Inter Miami superstar will unveil the monument virtually rather than in person for security reasons.

The eight-time Ballon d'Or winner will also meet Bollywood superstar Shah Rukh Khan and former India cricket captain Sourav Ganguly during his whirlwind trip to Kolkata.

Ahead of his arrival, Messi said it was an honour to visit India and interact with the fans.

"India is a very special country and I have good memories from my time there 14 years ago -- the fans were fantastic," Messi said in a statement.

"India is a passionate football nation and I look forward to meeting a new generation of fans while sharing the love I have for this beautiful game."

After Kolkata, where Messi will play a short friendly match, he will head to Hyderabad, Mumbai and New Delhi.

In Hyderabad he will attend a concert in his honour and play another friendly.

He is reportedly scheduled to meet Modi in the capital.
