Luton Town felt they should have had at least one penalty as they were held to a 1-1 home draw by Pompey.
The Hatters dropped points at home for the first time since September but were left frustrated as the Blues hit back to find an equaliser and then settled for a point.
But with boss John Still handing media reponsibilities to coach Hakan Hayrettin, Luton were unhappy that the referee had ignored their claims for a spot-kick after some grappling in the area from Johnny Ertl.
Hayrettin said: ‘The referee warned him about holding in the box and then he did it as the corner came in.
‘From my own stance, that’s a penalty and it happened twice where Jonathan Smith was held.
‘I thought we had a good shout for a penalty but it wasn’t to be.
‘We’ve had two very tough games in three days and to play the way we did was a credit to the boys.
‘The pleasing thing for us was that we got stronger as the game went on and if there was going to be a winner then it was going to be us.
‘But we’ll take the point.’
While Pompey were perhaps understandably happier with a point than their hosts, it meant Andy Awford’s side were prepared to run the clock down when they could during the second half.
Hayrettin said: ‘It was frustrating for us and we could see what they were doing.
‘We didn’t play as well as we could in the first half.
‘Then we huffed and we puffed but we couldn’t break them down at the death.
‘But we have this ethos at the football club that stems from the manager down – we’ve got to work hard.
‘Credit to the boys because they continue to work hard until the 90th minute in every game that we play.
‘To be where we are at this stage in the season in the table is fantastic and if you speak to any Luton Town supporter, I’m sure they’ll take that all day long.’
