Jack O'Connell insists United's focus is Tuesday's clash with Brentford, despite a trip to Elland Road on the horizon.
On the challenge his former club will pose, O'Connell remarked: "It's going to be a completely different game, Rotherham were really physical, Brentford are more of a passing side.
"They move the ball well and will relish this big pitch. It's going to be tough, but I'm confident we will overcome it."
The defender added: "We've not even talked about Leeds, the focus is on the next game, it's about preparation and then recovery for the next game after that.
"All we can do is take care of our business, we've got five consecutive clean sheets now and the next challenge is beating Brentford."
