Leeds have apologised to Derby for spying on their training and will remind head coach Marcelo Bielsa of his responsibilities.
The build-up to Friday night’s 2-0 win over Derby was dominated by claims from the Rams that a man was caught outside their training ground on Thursday.
Derbyshire Police were forced to intervene and it transpired the individual was an employee of Leeds, who was watching a training session.
A club statement read: “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.
“Our owner Andrea Radrizzani has met with Derby County’s owner Mel Morris to formally apologise for Marcelo’s actions.
“We will make no further comment on this matter.”
