Plymouth manager Paul Sturrock acknowledged football can be a cruel game after his team were beaten by a 90th-minute goal at Derby.
Miles Addison punished a mistake by goalkeeper Roman Larrieu to thump a header into the net for the winner.
Larrieu had told his defenders to leave Gary Teale's corner to him but then left the ball and Addison undid all Plymouth's hard work.
Sturrock explained: ``Roman called for it, he said he was going to come for the ball so the players left it to him and the next thing it's in the back of the net.
``I am gutted because the players gave everything they had.
``It looked as if our hard work and desire was going to get us a result, but it's a strange game and it can kick you in the teeth at times.
``I thought we had weathered the storm, in fact a minute before the goal we should have scored at the other end.
``We have now got seven days to wait until our next game but I wish we had one tomorrow to get this frustration out.''
Derby manager Nigel Clough was delighted with the way his team kept going to get a late winner for the second home game in a row.
The Rams scored towards the end of their opening game of the season against Peterborough and Clough admitted: ``It's important at home that you get results.
``I thought we deserved to win on the balance of play. We were a little bit tentative early on for some reason but when we got going, we dominated possession.''
Clough has called for goals from all over the pitch and Addison has responded with two already.
Clough said: ``I think he's our joint leading scorer now. The two centre-halves are a threat and we put good balls into the box and looked pretty dangerous from set plays.
``I thought we were dangerous from corners and free-kicks against a side that are good themselves at set-pieces.''
Derby's celebrations were muted by what looked like a serious injury to striker Steve Davies, who was stretchered off early in the second half after falling awkwardly in the box.
Clough said: ``Steve is strapped from thigh to ankle but we don't know what the problem is at the moment. It could be a knee, ankle or both.''
