Peter Ridsdale (born 11 March 1952) is an English businessman and advisor to the owner at Preston North End. He was until December 2011 the Chairman of Football Operations at Plymouth Argyle. Ridsdale was previously the chairman of Leeds United, Barnsley and Cardiff City. History Leeds United Ridsdale became chairman of hometown club Leeds United in 1997 and enjoyed success in the first four years of tenure as Leeds reached the UEFA Cup semi-final in 1999–2000 and the UEFA Champions League semi-finals in 2000–01. During this time he enjoyed a good relationship with the Leeds fans. However, once the full extent of what Ridsdale and his board had done at Elland Road was discovered by the fans this relationship vanished and he is now best remembered by Leeds supporters for the financial and relegation nightmares that the club found themselves in, going from a club competing in the UEFA Champions League to a League One club in the space of six seasons. Under Ridsdale's stewardship the club borrowed £60m against future gate receipts, effectively gambling on Leeds qualifying for the Champions League in successive seasons, which they failed to do. Ridsdale has repeatedly denied any blame with regard to the later situation of the club but has also conflictingly admitted it was a mistake to allow David O'Leary to spend so lavishly on players. Ridsdale also claimed that he would have saved Leeds from subsequent relegations to the third tier of English football and the debt his board had incurred in the name of the club. The fact remained however that by the time Ridsdale stepped down in March 2003, Leeds were £103 million in debt and failing on the field. After Leeds' relegation to the third tier of the English league system for the first time in their history Ridsdale said he was "deeply saddened" by Leeds's relegation but stated that he did not believe that events during his tenure as Leeds chairman were in any way responsible for the club's current plight. Barnsley He was also the owner of Barnsley for a while, rescuing them from folding after dropping from the Premier League to Division Two and loss of revenue from the ITV Digital collapse. Some saw him as a major mistake at Barnsley as he nearly made the club go into liquidation before Gordon Shepherd and Patrick Cryne took over at Oakwell. Cardiff City He became deputy
