Robbie Rogers admits Simon Grayson's departure from Leeds United has him concerned.
The USA midfielder joined Leeds last month from Columbus Crew.
"Obviously the old manager wanted me in and he's gone already," Rogers told the Yorkshire Post.
"Now that I'm here I'll need to prove to whoever's going to be the manager that I want to be here and want to stay.
"It's really strange when you come to a new place and everything changes only a week after you sign. But that's how life is and that's how football is. I've got to get used to it."
