Rooney completed his first game of the season against Chelsea on Monday, after which he thanked the United fans for their support.
Since then, Chelsea have signed Samuel Eto'o, which seems to have ended any chance of Rooney leaving for Stamford Bridge ahead of the transfer window closing on Monday night.
And now he is preparing for one of United's biggest games of the season.
"I felt he played very well the other night and he's looking in good condition and is mentally in good shape too."
Moyes declined to enter into further discussion on Rooney, preferring instead to underline the stance United have taken throughout the summer.
"We told you and everybody else from day one so I don't think there's anything else to add today," he said.
Moyes was no more forthcoming on United's pursuit of new players.
The club have had another bid rejected by Everton for Marouane Fellaini and Leighton Baines this week.
