Gyan has scored 51 goals for Ghana, and six of those have come at the World Cup, where he featured in 2006, 2010 and 2014.

Those feats make him both his country's all-time record goalscorer, and Africa's top goalscorer at the World Cup finals.

He turns 37 two days before Ghana's Group H opener against Portugal on 24 November, but says his age is no barrier to playing in Qatar, citing the example of another African great.

"I haven't announced my retirement," he said.

"Anything can happen, you know. It's happened before, talking about Cameroon in 1994, with Roger Milla coming back from retirement to play in a World Cup."

However, Gyan has not held conversations with Ghana coach Otto Addo or technical director Chris Hughton, who have been busy bolstering the squad's options with members of the diaspora such as Brighton defender Tariq Lamptey and Athletic Bilbao forward Inaki Williams.

"Honestly I haven't spoken to anybody at all," Gyan said.

"It's part of the plan. I just want to make sure I see how my body reacts first. I just need to get to some level and then I can say I'm ready.

"Everything looks positive, so we'll see what happens. There might be a surprise."
