Speaking on The Overlap, brought to you by Sky Bet, Rooney, while acknowledging similarities between De Bruyne and Gerrard, noted that the City playmaker stands slightly ahead in terms of offensive output.
"Very similar, and in my opinion, just a little bit ahead in terms of attacking points to Stevie," he said. "Similar traits to what Stevie is. He was more of an all-around player but I think in that attacking period, De Bruyne was incredible.
"City got to make a decision, and they have probably at the right time. Now, with FFP, you can't keep a player at the club for what he's done. You obviously have to go and replace him. But in terms of a player over the last, you know, 10 years, he's been there. It's incredible."
