AC Milan coach Leonardo was left in awe of two-goal Wayne Rooney in last night's 4-0 thrashing by Manchester United.
The Brazilian believes Rooney can only get better as he hit goals No29 and 30.
Leonardo said: "Rooney can grow up even more because he is still young. He's a complete player, strong, fast and he works hard.
"He does a lot of incredible movement and he's playing in a system that is perfect for him. United play at such speed and often on the counter-attack. That system, with Rooney, is incredible."
