Milton Keynes Dons manager Karl Robinson refused to blame the loss of four players for his side's poor performance in a 3-0 defeat at Carlisle United.
The Cumbrians had picked up four straight losses, but first-half goals from Lee Miller and Brad Potts set up Carlisle's first double of the season and David Amoo's header just before the hour-mark proved to be the clincher against a Dons side that never really got into gear.
Robinson said: "The players let themselves down. Carlisle played well, but my players let themselves down and they know that.
"We have problems all over the park. Carlisle were the better team and they had more hunger and desire than us.
"We were the second best team in the league in December and the loss of four players is bound to have had an impact.
"We have lost some quality and it's hard to replace them.
"The men on the pitch should have done better and I want to bring four players in.
"I will make mistakes, but my attitude won't be as bad as some of the players.
"Longy (Chris Long) looked a threat, but he was isolated on his own. Some may have played their last game for me."
By contrast Carlisle manager Graham Kavanagh praised the "excellent " performance of his team.
He said: "The mindset of the players was right. Some of our performances have not been bad, but we haven't put the ball in the net and we did that.
"It was an excellent performance and this is one of a number of wins we need to get us moving up this league and to keep us in the division."
Kavanagh had special praise for Amoo, who scored a goal and created another.
"He has been the difference this season," said Kavanagh. "Without his goals we would be in the bottom four. He has been a talisman for the team."
Kavanagh also hailed the performance of teenage midfielder Potts, who scored the first goal of his senior career in the first half.
The Cumbrians boss added: "It was his first goal and it will stand him in good stead for the rest of the season."
