Football fans will be able to bid to play in their team's colours as part of this year's Football Aid.
Visitors to Football Aid's web site, www.footballaid.com, can bid for positions in Scottish or English charity teams that will play in the strip of clubs including Arsenal, Manchester United and Celtic. The teams will play charity matches at professional stadia.
Football Aid is organised by the charity Field of Dreams, which hopes to raise about £500,000 with the event. Money raised will go towards diabetes-related projects and a range of charitable organisations nominated by participating football clubs and authorities.
There are also plans to expand Football Aid into Europe.
Grahame Paterson, a director at Sport Aid, said: "Football is such a powerful attraction and we recognised that if we were to work with some of the top clubs in Britain we'd generate significant interest and be able to raise some serious money in the process."
The online donations are being managed by internet payment company WorldPay.
