The eight-team pre-season tournament, won by Tottenham Hotspur two years ago, starts on July 12 and runs for nine days.

The other teams confirmed include South Korea's Sungnam Ilhwa, Japan's Shimizu S-Pulse, Udinese of Italy, and Chivas Guadalahara of Mexico, Yonhap news agency reported.

The draw will be made on Tuesday.

The tournament began in 2003 "to overcome ideological differences among nations and bridge race and religions" and "help realise world peace through football". It is run by the Sun Moon Peace Football Foundation.

Reading go into the tournament after a hugely successful Premier League season that saw them narrowly miss out on a place in Europe, finishing eighth, one point behind Bolton Wanderers.

Wanderers, with Sammy Lee at the helm after Sam Allardyce's shock departure to Newcastle, had an equally impressive campaign, qualifying for Europe for only the second time in their 133-year history.

Lyon will head to Korea as French champions once again but without coach Gerard Houllier who announced on Friday that he was leaving to take a sabbatical from football.

The former Lens, Paris Saint Germain and Liverpool manager led Lyon to two French league wins and to last year's quarterfinals of the Champions League.
