Leeds United apologizes to Derby County over 'spygate'
Ahead of Friday's Championship game in English football's second tier between Leeds and Derby County, Bielsa admitted to sending a spy to watch the opposition at their training ground on Thursday.
On Saturday, Leeds said its owner Andrea Radrizzani had met with Derby County counterpart Mel Morris "to formally apologize for Marcelo's actions."
"Following comments made by Marcelo Bielsa yesterday the club will look to work with our head coach and his staff to remind them of the integrity and honesty which are the foundations that Leeds United is built on," said a Leeds statement on its website.
The incident has been dubbed "spygate" by Britain's media.
