Nottingham Forest's first-half performance against Charlton Athletic annoyed Stuart Pearce so much that he could not forget about it, even when his side came back to claim a point.
Forest were outplayed by Charlton for much of the first-half at the weekend and they came in at the break 1-0 down, as a result.
It was a terrible showing from Pearce's men, but after a rollicking at half-time they returned to the field much improved.
Robert Tesche's belting strike rescued a point for them from the game, but Pearce was still left raging with the display in the first-half, according to Michail Antonio.
"Even at the end of the game, he still talked about the first half," Antonio told BBC Sport. "He told us it's not good enough. He said it made him sick to the stomach."
The draw means that Forest are still playing catch-up on the playoff places and they are going to need to add more consistency to their game if they are to make them.
Two impressive wins over Norwich City and Wolverhampton Wanderers appeared to put the Reds back on track, but a defeat to Birmingham City followed by this failure to grab the three points has led to further questions being raised.
Forest are now three points away from the top-six and although that gap is not insurmountable, a run of two wins in 14 matches is not likely to help them achieve their aims.
The Midlands club's next game comes this weekend, when they take on Rotherham United and it should be a good chance for them to get back to winning ways.
The Millers have struggled for form of late and look set to be fighting against relegation, meaning Pearce's men are likely to be keen to capitalise on a good opportunity.
