Former undisputed heavyweight champion of the world Lennox Lewis has said that Team GB's Anthony Joshua has a "great future ahead of him".
Joshua, 22, became the Olympic super-heavyweight champion yesterday with a thrilling countback win over Italy's Roberto Cammarelle.
"When the going gets tough, the tough gets going. Joshua proved that and really wanted it. It showed his fitness was great as well," said Lewis, who won super-heavyweight gold at Seoul 1988.
"In four years [since he started boxing] he has achieved so much. Heavyweights are known to mature later so it's a great achievement to beat an Olympian of excellence and a world champion.
"He can either stay amateur or go pro but he has a great future ahead of him."
Meanwhile, Joshua has expressed his desire to remain in the amateur game in order to compete at Rio 2016.
