"Five more minutes," will not make a difference, because yes, he's awake enough to be aware of Steve moving, and he'd really like a coffee, and also would really like to sleep more, and he says it anyway.

He's got one leg over the arm of the couch, the other off the edge with his heel on the floor, one arm under his head for a pillow and the other currently over his eyes. The picture of sleeping beauty, clearly.

He lifts the arm after a few moments to glance at Steve. And his mess of hair. All that time away and getting rid of the good ol' boy Captain, replaced with the wanted criminal on the run, looks good on him. "Maybe even five more hours."
