Michael Appleton told referee Carl Berry: You lost the plot.
Berry was the central figure in Pompey’s 1-0 defeat to Oldham today.
The official had a nightmare performance and failed to control a game which descended into chaos.
And to make matters worse the official sent off Jordan Obita and, in a case of mistaken identity, Oldham’s Cliff Byrne.
Obita got involved in a tussle with Latics defender Connor Brown, but the wrong man walked for the visiting side.
That capped a display where the official got a string of decisions wrong.
Appleton pulled no punches about his performance.
He said: ‘Let’s face it,- the referee lost the plot today.
‘Nobody knew what was going on in the second-half.
‘I haven’t spoken to Jordan yet, but I will over the weekend.
‘I haven’t seen the sending off.
‘I will decide then what we are going to do about.’
The display of the official failed to mask what was a poor Pompey performance against a side who gave them a physical challenge.
Appleton said: ‘We didn’t have enough shots in the second-half, but we kept working hard.
‘That’s what I want, but we have to handle physical team better.’
