Experienced French trainer Herve Renard has made a shocking revelation about Ghana's all-time leading goalscorer, Asamoah Gyan, claiming the former Sunderland star was lazy in training.

According to the Renard, who boast of winning the Africa Cup of Nations (AFCON) trophy two times, Gyan could have had a much better footballing career if he was dedicated and committed in training as he was during competitive matches.

Renard worked with Gyan when he was assistant coach of the Black Stars during the 2008 AFCON which was staged in Ghana.

“The quality of Asamoah Gyan was amazing. I was always impressed with his timing of headers,” the Saudi Arabia coach said in an interview with TV3.

“He was a very good goalscorer, a fantastic player, an amazing player.

“But I have something to tell him. He was supposed to have a better career, but he was lazy,” Renard said while laughing.

“In training, he was lazy. He only likes games. But he was the most important player but I know him and he didn’t like the training, he only likes the competition, the games,” he concluded.

Gyan has scored 51 goals for Ghana, more than any player. He also has more World Cup goals (six) than any African footballer.

The 34-year-old is currently without a club after his short term deal with Indian side NorthEast United ended in January.
