Newcastle United manager Rafa Benitez confirmed last month that Atsu would miss the rest of the season and he has been out for over a month.
The injury ruled him out of Ghana's international friendlies against Japan and Iceland to be played on May 30 and June 7th.
The hard-working winger had a stellar campaign with Newcastle United as they finished 10th in the English Premier League.
“I can assure you I will be better than last season for sure, and I believe when am playing the fans will see a big difference in me,” he said.
The 26-year-old played 26 games and scored twice for the Toons.
Atsu joined Newcastle from Chelsea after spells with Everton, Bournemouth and Porto previously.
