Sturridge has been an inspiration since recently joining Bolton on loan from Chelsea until the end of the season, scoring a goal in each of his three appearances.
With limited opportunities for him at Stamford Bridge, the 21-year-old is making the most of his chance at the Reebok Stadium, as Coyle always knew would be the case.
"He's not surprised me. That's why I brought him to the football club," said Coyle. "I'm not sitting here trying to be smug, but it didn't surprise me as to how well Jack Wilshere did here when we had him on loan from Arsenal because of the belief I had in him as a player.
"I would say it's been all about giving these lads a platform to go and show their quality, and Daniel is now showing that.
"I believe if he continues as he has been doing then he will have a glittering career, but he's the one who has to deliver when he crosses the white line."
