Manager Steve Morison was furious at his team's "shambolic" defending in their 2-1 defeat at Hull City.
It was a calamity of errors for both goals. Mark McGuinness' woeful backpass to Dillon Phillips afforded Allahyar the opportunity to round the goalkeeper and put the ball into the back of the net for the opener.
And just minutes later, a poor clearance from McGuinness, which was mis-controlled by Cody Drameh into the path of Regan Slater, who slid the ball into Lewie Coyle's path and the Tigers man lashed home to double the lead.

Despite a spirited fightback, including a late goal for Aden Flint, Cardiff could not get back on terms. They had performed a tremendous turnaround win at Reading last week but just couldn't do the same on Humberside. The early defending left Morison fuming.
"Did we deserve anything out of it? On balance of chances, yes, and overall control and dominance in the second half. But it doesn't matter, we lost the game. I'm not going to fluff it up," he said.
"We were 2-0 down, it's like starting at a deficit, it's ridiculous. But I was really pleased with the second half. It shows you can dominate teams, I was just gutted we didn't quite get another goal."
On the defending, he added: "It's horrendous. I'm not going to focus on it. I'm going to focus on the second half because I don't want to create unnecessary headlines. It was shambolic stuff first half, well, the first 10 minutes."
The manager was, though, encouraged by the second-half display, spurred on by the introductions of creative forces Tommy Doyle and Rubin Colwill. Morison, however, believed it was simply because the players actually started carrying out the game plan.
"It wasn't the introductions [of Tommy Doyle and Rubin Colwill], it was the fact they carried out what we asked them to do; move them around, switch the ball, create pockets, play to our strengths. And we did that," he added.
"Rubin, Tommy and that were excellent. So was Oli Denham. I was really pleased with the second half."
