The 16-year-old produced a superb performance after being handed a senior start by David Healy with the Blues boss rotating his squad at Inver Park, handing opportunities to a number of Linfield’s U20 league champions.
Northern Ireland youth international Thompson is another exciting talent coming through the ranks at Windsor Park and has now racked up four Premiership appearances.
Glenavon teenager Luke McGerrigan, also aged 16, then scored his first goal in their 2-0 weekend win over Ballymena United just moments after coming off the bench at Mourneview Park.
After achievements from McGerrigan and Thompson, we take a look at the 11 youngest players to score in the top-flight this season.
