Lee Murray was found guilty of four charges following a trial at the High Court in Inverness on July 30.
The 53-year-old also sent the child indecent images of himself and inappropriate messages while proposing to meet up with her.
He was found guilty of raping and sexually assaulting her in his vehicle on various occasions in the Inverness area.
While on bail, the former Thistle Girls FC head coach sent sexual messages to an adult female, who was posing as a 14-year-old girl on a social media app.
Murray, who believed he was talking to the underage child, then engaged in a video call on WhatsApp where he indecently exposed himself to the same person.
The offending took place between January 2021 and October 2022.
On September 10, at the High Court in Edinburgh, Murray was given a sentence of five years imprisonment with an extended period of two years and a non-harassment order banning him from contacting or attempting to contact his victim for three years.
His name has been added to the sex offenders register indefinitely.
Scotland’s Procurator Fiscal for High Court Sexual Offending, Katrina Parkes said:
“Lee Murray held a position of trust within the local community while committing this horrific sexual offending.
“He poses a danger to children and will now have to face the consequences of his actions.
“COPFS prosecutors are committed to securing justice in child sexual abuse cases.
“I would urge anyone aware of or affected by similar crime to report it and seek support.”
