Scholes 36, decided to pull the curtain down in a glittering career at Old Trafford. The former England international made his debut for United in 1994, making 676 appearances, will now join the coaching staff at United next season.
Rooney has always been a huge admirer of the midfield maestro and suggests the hole left by Scholes retiring will be hard to fill.
The forward said; "He'll be missed greatly. I just heard the news this morning," Rooney.
"We knew he'd make a decision but didn't think it would be this quick. We're all sad to see him stop playing.
"He's been great for United and England and he'll be missed by all of us.
"He hasn't started that many games of late and I'm sure that's come into his head and he's made his decision.
"But he'll be a big miss for us. He's the best I've played with and against.
"He's only small but it's so difficult to get the ball off him. Every United fan will miss him."
