Man Utd striker Rooney delighted with victory over Norwich
Sir Alex Ferguson is demanding no loss of focus, or status, which Rooney feels was underlined by his team selection.
"It hasn't been hard not thinking about Tuesday," said Rooney.
"Norwich was a massive game for us and we wanted to extend the gap at the top of the league.
"The manager put a lot of experienced players out and made us aware it was more important."
