Michael Appleton was adamant Pompey were denied a nailed-on penalty which could have proved key against Leeds today.
But the Blues boss warned his men they couldn’t linger on the decision after being held to a 0-0 draw at Fratton Park.
Darren O’Dea clearly handled the ball in the box before the break, but referee Phil Gibbs waved play on.
Appleton explained replays confirmed it was a spot kick.
He stated his men have to move on from that quickly though, with the Blues now entering the defining period of their season.
Pompey currently sit one off the bottom of the table - and five points from safey.
Appleton said: ‘I felt it was a blatant penalty and looking back at it told me what I thought was right.
‘The attitude was right and we deserved to be ahead at half-time.
‘Apart from a three or four minute spell in the second-half I thought we were reasonably comfortable.
‘But we’ve got to move on quickly now.
‘Next week is the start of eight crucial games in a month. There’s a lot of points to play for.’
