JIM Goodwin last night aimed a dig at Celtic left back Greg Taylor and claimed St Mirren had a soft penalty awarded against them.
The Paisley club were trailing their Glasgow rivals 1-0 when Taylor went down following a challenge by Ryan Flynn in the 78th minute.
Referee Don Robertson awarded a spot kick which Odsonne Edouard converted and showed Flynn a yellow card.
“I’ve watched the penalty back and we’ve had a number of incidents similar to that this season go against us,” said Goodwin.
“We played against Hibs (in the 2-1 defeat that St Mirren suffered last week) and there was a slight bit of contact on (Jamie) Murphy.
“It’s the same tonight. There’s a slight touch on Taylor’s shoulder, but I don’t think it’s enough for his legs to just crumble beneath him.
“Unfortunately that’s the way the game’s going. We’ve had our fair share of soft penalties go against us this season.”
Meanwhile, Goodwin revealed that Jamie McGrath, who went off injured early in the first-half, is set for an extended spell out.
“It’s not looking good for Jamie,” he said. “He’s dislocated his shoulder, sometimes they can be a couple of weeks depending on how serious it is.
“If he needs surgery then his season’s probably over, so we’re going through a bit of a difficult patch in terms of that.
“We’re missing Kristian Dennis for a number of weeks with a serious achilles problem, and Eamonn Brophy looks as if he’s got a problem with his foot which could be a lengthy one as well.
“Unfortunately, things are going against us in that respect at the moment, but that’s why we have a good squad and it gives an opportunity to someone else.
Goodwin added: “We won’t get too disappointed about tonight. There’s lessons to be learned for sure.
“Of course we’re disappointed to lose the game. The first half we did okay, I don’t think there was much in it in the opening 45.
“The goal is disappointing, obviously we know Tom Rogic favours his left foot and we didn’t do enough to put him onto his right and it’s a brilliant finish from him.
“The second half I thought we were poor. Credit to Celtic, I thought they were very good and I thought they upped the tempo in the second half. Their movement was a lot better and they caused us a lot of problems.
“That said, it was still only 1-0 up until about the 80th minute. Then we had a four or five minute spell where things started to crumble and now we’re standing on the back of a 4-0 defeat.
“We’re still in the driving seat for a top six spot. We’ve still got games in hand on other teams around us.
“We’re not going to be judged on games like this. Hopefully we’ll give a better reflection of ourselves at Pittodrie on Saturday.”
