The story in German magazine Sport Bild claims there are questions to be answered about the identity and age of Jatta, who fled The Gambia and arrived in Germany as a refugee in 2015.

Jatta signed for Hamburg as an 18-year-old in June 2016. But if the claims are legitimate, they'd mean he'd now be 23, not 21, and therefore would no longer have been a minor on arriving in Germany, which would have complicated possible refugee status.

"The topic is known here, the control committee will investigate the facts," said Rainer Nachreiner, a committee chairman for the DFB (German FA).

A Hamburg district administration spokesperson said the city would "examine the case intensively and follow instructions."

Jatta, a forward, has proved a success at Hamburg, who now play in Germany's second division, and has drawn praise in some quarters for being a positive example of refugees in Germany.

His initial three-year contract with Hamburg was extended for a further three years, and the player has a residence permit as a result of his professional contract.

Sport Bild quoted the club's CEO Bernd Hoffmann as saying Hamburg relied on the player providing valid documents.

Jatta had always shown himself to "an impeccable sportsman and reliable teammate who quickly integrated into our team and into our club," he said.
