The striker hit the post and then had a goal ruled out for off-side as we sought a breakthrough against a stubborn PSG side in the first of our three group stage matches at the pre-season tournament in Ploufragan.
The French outfit subsequently hit the woodwork themselves in the 25 minutes each way contest, but our chance was taken six minutes from time when Joe Pritchard was felled in the box and Harrison buried the spot kick.
In all we had nine attempts at goal, four of which were on target, while restricting PSG to one shot on target and two off.
