Dundee manager Neil McCann believes his side should have had a penalty in their 1-0 defeat to Celtic at Parkhead on Saturday.
The Dark Blues battled and played some good football to run the champions close at Celtic Park.
However, a second-half goal from Olivier Ntcham was enough to end Dundee’s three-game unbeaten run in the Scottish Premiership.
Dundee had a handful of good chances to equalise in the last half-an-hour and boss Neil insists they should have had a penalty after Jack Hendry and Cristian Gamboa clashed heads in the home box.
“We should have had something from the game, it should have been a penalty,” Neil said.
“I think it’s a penalty, I don’t know if it’s accidental but big Jack’s gone in and won the header then he’s been cleaned out by Gamboa.
“I don’t see why it’s not a penalty, anywhere on the pitch that’s a free-kick.
“I hear it all the time and it’s what angers managers, why not in the box?
“He’s been cleaned out, accidental or not, he’s been cleaned out and it should have been a penalty.
“The linesman said he felt that it wasn’t won cleanly but it was a 50-50 header, well my big centre-back got a lovely wee medal to take away from Celtic Park with the opening of his eye and that, for me, just cements it.”
Neil’s opposite number, Hoops gaffer Brendan Rodgers, thought referee Andrew Dallas made the right call not to award a spot-kick.
Rodgers said: “I think when you’re the away manager you look for something then, at that moment when your player goes down in the box, you can get a wee bit excited looking for the penalty.
“If you watch it again, Hendry clips the ball over Cristian’s head, then Cristian actually jumps first so he’s on his way.
“He can’t stop, he can’t move because he’s in mid-air and then Hendry just gets there a fraction before.
“If that’s outside the box then OK, it’s a clash of heads and it’s unfortunate.
“That’s exactly what happened, the physios come on, it’s a bounce ball and we play on.
“It’s in the box though and I’d expect Neil to look for a penalty but I thought the referee made a really good decision.
“Unfortunately, in the end, both boys had to come off.”
