The singer, 22, shot to fame with the boy band following their third placed finish in the 2010 series of The X Factor. Following the release of three incredibly successful albums, the band were rumoured to be worth a combined £59.3 million.
Despite international stardom, the Bessacarr-born singer still owns a season ticket at the Keepmoat Stadium, and fulfilled a life-long dream by signing with the Rovers on non-contract terms having impressed in a charity match with the club.
His debut for Doncaster's reserve side came against Rotherham United on 26 February 2014, in which he appeared as a 65th minute substitute to a crowd of over 4000 - including One Direction fans from America and Australia.
Following the Rovers' final day relegation from the Championship, the Doncaster Free Press is reporting that the singer is in talks with ex-chairman John Ryan concerning a proposed takeover of the club.
Ryan, who owned the club before it was sold to the Keepmoat group, has plans to form a trust to take over the relegated side.
The playing squad are keen on the idea, knowing that, despite his stardom, he is still a local boy at heart.
Luke McCullough, who featured in Tomlinson's reserve debut, said: “He’s made a lot of money for himself and he’s broken America but he’s a season ticket holder.
“It would probably be a dream for him to be involved with the club and as players we don’t mind who runs it.”
It would be a logical move for the club, with Tomlinson's wealth and fandom combining well with Ryan's experience of management, and it could only further help build the reputation of the side - a reputation that shot through the roof following the star's debut.
