The club are enjoying a good season in the English Championship
Italian businessman Andrea Radrizzani is the new co-owner of Leeds United.
He has acquired a 50% stake in the Championship club from Massimo Cellino who was banned from all football activities for 18 months after breaching the FA's football agent rules last year.
In remarks to the Leeds United official website, Radrizzani of the ASER Group said: "I am delighted and proud to have acquired a 50 per cent stake in such a prestigious football club as Leeds United. I am excited by the challenge ahead and I will work alongside Massimo and everybody at the club to make Leeds United as successful as possible.
"I am fully aware of the great heritage and traditions of Leeds United and I will endeavour to be a fitting custodian on behalf of the many thousands of Leeds supporters, who are the lifeblood of the Club.
"I am making a long-term commitment to Leeds United and will work to bring stability through ongoing investment. I aim to bring sustainable growth. I won't do anything that will put the Club's future at risk.
"Through working in the sports industry for many years, I have developed a great passion for the English game and I am honoured to have become joint owner of one of the country's biggest clubs.
"I am very impressed the job Garry Monk has done this season and I will do all I can to support him and the team moving forward."
Leeds are performing well this season in the English second tier under the management of former Swansea boss Garry Monk, over a decade on from their last appearance in the Premier League.
The Yorkshire club are currently 5th in the league and seven points off the automatic promotion places.
Monk (37) took charge in June on a rolling one-year contract.
Prior to his appointment, Leeds had had six permanent managers since the start of the 2014-15 season.
