Manchester United goalkeeper David de Gea is the latest player to praise striker Wayne Rooney for his midweek performance against Bayer Leverkusen.
Rooney scored twice in a comfortable 4-2 win over the German outfit on Tuesday night and has been commended in recent days for his display, in which he scored his 199th and 200th goals for the club.
Speaking to the club's official website, De Gea said: "Not only did he score goals, he played some great football, worked hard, brought dynamism to the team and played a really great game."
The 22-year old also went on to mention the benefit of Rooney and Van Persie's partnership, adding: "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."
United earned a crucial win over Leverkusen that gave the Red Devils a near-perfect start to their Champions League campaign, and De Gea says that the team are in good shape ahead of the Manchester derby this Sunday.
He said: "The victory has boosted our confidence for Sunday.
"It was important to kick off with a win; we made a good start and got the three points, which gives us piece of mind.
"We've since had a few days to prepare for City and we're looking forward to the match."
Manager David Moyes could be without Danny Welbeck who is still recovering from a knee injury, as the Scot prepares to take charge of a United team in one of the fiercest derby matches in the world for the first time.
