Cole, himself having scored 121 goals in 275 appearances for United, felt that Rooney was keen to step up in the absence of Cristiano Ronaldo and prove his class.
"Rooney has started the season really well. He's ready to step into Ronaldo's shoes. His attitude is 'I'm top, and I'm going to prove it'. He's the man to get 25-30 goals this season," Cole said, according to United’s official website.
The ex-England ace also urged fans to be patient with Dimitar Berbatov, after the Bulgarian endured a mixed first season. Cole acknowledged that the high expectations that greeted Berbatov have yet to be met, but emphasised the importance of the stylish forward’s contributions.
"It's not easy coming to United in your first season," he added. "The spotlight is on you straight away and everyone expected Berbatov to get 30 goals last year.
"I don't think he's that type of player, but he brings something different to the team. He's so elegant.”
Cole was also looking forward to seeing new signing Michael Owen make an impact.
He continued: “Then there's Michael Owen. There aren't many natural finishers around. Sir Alex told me that if he keeps Owen fit he'll get goals."
