New Sunderland striker Asamoah Gyan insists his World Cup heartache is behind him and that what happened in South Africa can only make him a better player.
Gyan was one of the stand out performers in Ghana's run to the quarter-finals, scoring three times as they became something of a Cinderella team.
However, Gyan will also be remembered for missing a last-minute penalty against Uruguay that would have put Ghana into a semi-final with Holland.
“You have to be strong and move on,†said Gyan after completing his £13.1m move from French club Rennes.
“It was a major, major disappointment for me but that’s in the past now.
“I have to concentrate on the positives, I had a good tournament, I’ve kept mentally strong and I’m looking forward to the future challenge with Sunderland.â€
Sunderland will now boast a front two valued at well over £20m as Gyan teams-up with the club’s previous record transfer Darren Bent, who cost £10m.
