Despite being a club record £8.2million arrival in 2008, the Swede has struggled to live up to his billing. His first two seasons in England yielded only 10 goals and Elmander was largely derided as an expensive flop.
Yet, instead of ditching the former Toulouse striker at the first available opportunity, Coyle continued to show faith in the 29-year-old.
His reward has been an excellent series of performances so far this term, with the added benefit of three goals.
Ahead of Sunday's high-noon confrontation with Manchester United at the Reebok Stadium, Coyle has revealed he never had any doubts over Elmander's contribution to the Trotters' cause.
However, as a former striker himself, the Bolton chief is acutely aware the difference finding the net can make.
"As a striker, if you are not amongst the goals a part of you will be down," said Coyle. "We did try to help but the biggest influence has been Johan himself.
"We can impart any knowledge or perceived wisdom but he is the one who has to deliver when he crosses the white line. Now I believe he has turned the corner and I am sure there are more goals to come."
