On Cristiano Ronaldo, Rooney told MUTV: "He's a joy to play with. He has been amazing and hopefully he can continue that until the end of the season and help us win the league."
Ronaldo may have grabbed the headlines in recent weeks with his goalscoring exploits, but he is building on strong foundations laid by his team-mates.
Rooney said: "They've been brilliant, but not only those two - Owen (Hargreaves) and Michael (Carrick) were brilliant in front of them and Wes (Brown) and Patrice (Evra) as well.
"As a team we're defending well and Edwin (van der Sar) and the back four in particular are helping us. We know if we keep a clean sheet, we're going to score goals."
He added: "I'm just delighted with the way I'm going at the minute and hopefully I can keep going."
