The 25-year-old has scored 15 goals in 23 starts since moving to Ewood Park from Cardiff City in January for £200,000.
"I really like the look of Gestede," Sutton told the Lancashire Telegraph. "I think he's a little bit raw but I can't remember the last time I saw a centre forward that dominant in the air like him – I was mightily impressed.
"He's superb in the air, there's no doubt about that, and now I would love to see him pin people in and around the box because he's got a nice touch and he holds the ball up well.
"He's still relatively young and if you are Cardiff then you must be kicking yourself for letting him go."
Gestede has scored three goals in five appearances for Rovers this season.
