David Moyes confirmed Darron Gibson may require an operation in the summer and backed the midfielder to find the net more often next term.
The former Manchester United man opened the scoring at Goodison Park on Saturday when his deflected strike found its way past QPR stopper Julio Cesar in the 2-0 win.
It was only the 25-year-old's second goal since arriving in January 2012, with a series of injuries breaking up an otherwise impressive first 15 months on Merseyside.
And Blues boss Moyes believes there is more to come from Gibson, especially in front of goal, once a troubling thigh problem has been addressed at the end of the current campaign.
He told the media at Monday's press conference: "After the game on Saturday, I was asked about Darron Gibson's goal and his shot - I think he could do it more and with more ferocity as well because he's got a great shot on him.
"But he has got a bit of a problem at the top of his thigh which I think will need some form of operation at the end of the season."
Gibson's distribution and calmness in the centre of the park has already made him a fans' favourite at Goodison - and his manager is also pleased with what he has brought to the side.
"I think that what he's given us is that he's good on the ball," he said.
"He's got a better range of passing than maybe some of the other midfielders we've got. He's a different type.
"He can score from a shot and we're hoping that he can do that more regularly. That was one of the main reasons for bringing him in - to start to try and get some more goals from midfield.
"I do think overall he's had an impact. He's maybe had a dip midway through when he came back from injury but his form's good and he's in good condition now."
