Swindon boss Paolo Di Canio labelled the performance of some of his players "unacceptable" despite a 1-0 win at Morecambe which took them a step closer to the League Two title.
Paul Benson scored the only goal of the game less than a minute into the second half when he converted from close range after Lee Holmes headed Joe Devera's cross perfectly into his path.
But Di Canio was furious with some of his side's younger members, calling them "lazy" and "unprofessional".
After the game, the Robins boss raged: "We have won but I am not happy. There were five or six players whose attitude was unacceptable. I can't accept the attitude of five or six players.
"Paul Benson was an absolute warrior and ran his socks off and got his reward with the winning goal. Others did not put enough effort in for me. They didn't run for the ball and they were lazy. They think because they play well one week then they have made it and that is not the mentality I will accept."
"If I asked them they will probably think they had a great game but I know better than that and I was very angry with a few of them, especially in the first half. I could have taken about seven of them off at half-time but only changed (Luke) Rooney, and the second half was better, with the defence superb."
Morecambe boss Jim Bentley was left with plenty to ponder after an 11th home defeat of the season, and said: "It is massively frustrating because once again I thought we deserved something from the game and it was the same old story for us.
"I thought we had the better of the first half and I was happy at the break but then we fell asleep as the second half kicked off and you can't afford to do that against a side like Swindon.
"I must sound like a stuck record by now as every interview seems to be the same. I keep talking about this fine line between wining and losing and all too often we are falling the wrong side of that line.
"We are not doing a lot wrong and the commitment of the lads is terrific but we just need to turn it around at home and give our fans something to cheer about."
