Tommy Wright has slated the way Chesterfield FC defended in the 3-1 defeat against Notts County at the B2net Stadium.
And the Blues assistant manager, who watched the team plunge into the League One relegation zone as a result of the loss, advised a number of senior players to examine their consciences.
Wright - pictured - said: “We started very poorly. We never got out of the traps.
“We gave ourselves a mountain to climb. You cannot give another team goals, it is unacceptable.
“Our first-half performance was poor. We were second to the ball, the tempo was poor and it was fortunate that Notts County only led 2-0.
“Players have to take responsibility. They are not kids, they need to go home and look at themselves.
“We are playing some nice stuff but that is not enough. We have to defend better.
“If Barcelona defended like that they would lose games.’’
The result was Chesterfield’s fourth defeat on the trot and the team’s third defeat at home in the league this season.
He said that defender Dean Holden, who suffered a head wound during the first-half following a clash of heads and had to leave the field more than once for the flow of blood from the wound to be stemmed, had required four or five stitches.
Chesterfield have an opportunity to turn things around on Saturday when Hartlepool visit the B2net.
