A replica of Barcelona star Lionel Messi's foot made from pure gold has been unveiled in Tokyo.

Japanese jeweler Ginza Tanaka is behind the creation, which is valued at £3.5m, as a tribute to the Argentina international's playing achievements.

"I'm honoured to have my foot recreated in pure gold," Messi said via a video message.

"It's exceptional," BBC Sport quotes Messi's brother Rodrigo as saying. "You can see each line in the foot. It's an impressive piece of work."

Part of the proceeds will go to the prolific striker's foundation as well as to children who were affected by the earthquake and tsunami in Japan in 2011.
