Niall Currie was left disappointed that Coleraine's second goal was allowed to stand on Saturday, but his biggest gripe was about something closer to home.
The Portadown boss felt Matthew Shevlin should have been flagged for offside before putting the Bannsiders 2-1 ahead at The Showgrounds.
Currie though was left more frustrated by the performance of his side in the second half as the hosts ran out 4-1 winners in the end.
