He replied: “I think it is. It’s one where if it’s given against you, you’re disappointed. I don’t know what the boy can do there, obviously I’m happy we got it.”
Wright defended his players, despite suffering a late collapse against the Premiership pacesetters and put blame on referee Craig Thomson.
He said: “They deserved better, they deserved a better performance from the referee.

Dembele’s unstoppable spot-kick was the first of his three second-half goals after coming on as a substitute – having recently recovered from a knee injury.

“We’re glad he’s back because you can only play so long without a striker. But you can see the difference he makes when he comes in, being that reference point and then everyone else can move around him.
“He’s recovered well and he just needed that time to get training under his belt.”
Dembele has now scored 23 goals in his debut season in Scotland.
Scott Sinclair netted again and he is the top hitman in the Premiership with 14 goals.
Liam Henderson gave Celtic the lead in the sixth minute before Keith Watson and Dedryck Boyata (og) scored to give the Perth outfit the half-time lead.
Then came the penalty-kick award and there was only going to be one winner after that.
