After a run of poor form which saw his side suffer several heavy defeats, the head coach has parted company with the team.
The Whites are two points above the bottom of the table.
After a 16-year absence, Leeds returned to the top flight last season.
They had lost their past four games by an aggregate score of 17-2.
This has been the toughest decision I have had to make during my tenure at the club, taking into account all the success that Marcelo has had.
The good times returned to Elland Road after three incredible campaigns with Marcelo as our head coach. He brought a winning mentality to the club.
I have to act in the best interest of the club and I believe a change is required now that we are in the top flight. Results and performances have not met our expectations.
We find ourselves in a precarious league position and I feel now is the right time to bring in a new head coach, in order to have an impact in the final stages of the season.
More to come.
