ARSENAL have denied that they are holding trials after fake adverts emerged.
And fans have reacted angrily to the "scammers" taking money from parents, whose kids expected a trial.
The club added that they have reported the matter to the police.
They released a statement on their Facebook page denying any links with the trials.
One fan called Malina Kowalewska wrote: "Such a horrible thing to do. Many parents and kids must feel devastated right now. I hope they'll get those scammers."
Duane Okelly added: "Disgusting! It's one thing scamming parents out of hard earned money, but to wreck a child's dream like that is unforgivable!!"
They also encouraged anyone who had paid up to go to the police if they could not get a refund.
They wrote: "We are aware that Arsenal football trials are being advertised on goprofootball.co.uk.
"Arsenal Football Club has no arrangement with the company and there will be no football trials at our grounds this weekend.
