Williams, a lifelong fan of the League One side, was said to be considering a Wrexham-style takeover at Vale Park.
The 49-year-old former Take That star, whose solo hits include Angels, Let Me Entertain You and Come Undone, became the club’s president at the weekend and opened a new suite named after him.
But Vale, owned by businesswoman Carol Shanahan, say there are no plans in the pipeline for Williams to buy the club.
A Vale statement read: “We are aware of the ‘exclusive’ news that appeared in several national news outlets overnight and want to clarify the following:
“Robbie Williams has not made a bid to purchase Port Vale Football Club and there have been no conversations regarding that happening.
“Robbie and his team attended the match this past weekend, where he became club president and opened the suite that is now named after him.
“There are a number of positive club projects that both Carol and Robbie are exploring with the intention of anything delivered being in the best interests of Port Vale Football Club.
“As owners of the club, the Shanahan family remain fully committed to Port Vale FC.”
Vale are currently 20th in League One and lost 1-0 to Portsmouth on Saturday.
The eight-time Olympic gold medallist, who retired from athletics after the 2017 World Championships, will captain the Soccer Aid World XI FC against an England selection led by musician Robbie Williams.
Soccer Aid is an annual charity football match between the two teams, both comprised of celebrities and former professional football players.
The game is usually held in June but could not go ahead this month due to the coronavirus pandemic, so this online alternative is being used as a substitute in the short term.
The live tournament is being held to generate donations for Unicef to help stop the spread of coronavirus and limit the impact on children’s lives. Every one pound donated will be matched by the UK government.
The tournament consists of eight 1-on-1 matches between gamers and celebrities from England and the rest of the World.
Captains Bolt and Williams will face off.
The winner will be decided on the overall aggregate score.
The roster of both teams is absolutely impressive. In addition to stars from sports and music, some well-known esports figures will also be competing.
Joining Bolt and Williams at this year’s competition are singers Liam Payne and Olly Murs, Olympic athlete Mo Farah, Hollywood actor James McAvoy, as well as football freestyler and presenter Liv Cooke.
Usain Bolt said: “I’m excited to be able to captain the side again, albeit in a slightly different setting. It’s incredible to see Soccer Aid World XI FC in the game and I can’t wait to get going in eSoccer Aid for Unicef playing with the team. I’m looking forward to seeing Robbie and catching up with him as we play. I hope everyone enjoys watching and remembers to donate.”
