And Rooney, who has three of them, took his tally to 200 for United with a brace against the German side on Tuesday.
Goalkeeper De Gea was impressed with his performance, telling United’s official website: "Not only did he score goals, he played some great football, worked hard, brought dynamism to the team and played a really great game.
"It’s good for us that he and Robin score goals. It is important; they are key players and this year they will combine to great effect."
Midfielder Michael Carrick felt Rooney was unstoppable against Leverkusen and believes he has returned to his best. He added: "It was probably Wayne's best performance that I've seen for a while. It's great to have him in that form -- he can be untouchable when he’s like that.
"To have Wayne and Robin scoring and assisting is fantastic. Even if they're maybe not having the best of games they can always come up with something. I thought they played really well on Tuesday."
United face Manchester City next in the derby at the weekend and De Gea added: "The victory has boosted our confidence for Sunday."
