Sheffield United boss Danny Wilson felt aggrieved Charlton were given the free-kick which led to Johnnie Jackson's goal in Saturday's 1-0 loss.
The game was settled by Addicks skipper Jackson's stunning 21st-minute free-kick, although the gloss of the win was slightly taken off by a sending off apiece late on when substitutes Darel Russell and James Beattie saw red.
Wilson said: "We fully deserved something out of the game, I thought we were fantastic for large parts of that game.
"Is it dij'-vu from last week where Johnnie Jackson scored a fantastic free-kick [at Sheffield Wednesday].
"We are aggrieved to how that came about in the first place from the throw-in that was our's and then the foul that was allegedly committed was never in a million years a foul.
"But you've got to take your hat off for the execution, it was terrific. We started the game ever so well and in the second half we've completely run the show."
