Bolt had already posted on social media on Sunday saying that he had signed for a football team, with an announcement expected on Tuesday at 8am.
The 31-year-old called time on his decorated athletics career last summer, having won eight Olympic gold medals and holding world record times at 100m and 200m.
Bolt revealed to Sky Sports News in 2016 that he was planning for a football career after retiring from the track and said his ideal destination would be Manchester United – the club he supports.
American athlete Justin Gatlin previously believed the Jamaican could return to the sport for the Olympic Games in 2020 in Tokyo, Japan
Bolt’s final competitive race was at the London World Championships in August 2017 at the Olympic Stadium when his 100m farewell ended in a third-placed finish behind Gatlin and Christian Coleman.
