Plymouth Argyle manager John Sheridan has demanded improvement from his side after their fifth game without a win.
The Pilgrims have dropped out of the League Two play-off places, having picked up just two points from a possible 15 since Christmas.
"Two points isn't good enough in five games," Sheridan told BBC Radio Devon after their 1-0 loss to Luton saw them fall below fierce rivals Exeter City.
"We have to improve and pick up points," the 50-year-old continued.

|3 January: Drew 0-0 at York City|
|28 December: Lost 2-1 to Oxford United|
|26 December: Lost 2-0 at Newport County|
Argyle were a fixture in the play-off places from the middle of October until their poor run began on Boxing Day when they lost
"Five games ago we were looking really healthy and positive," Sheridan added.
"All of a sudden we've gone a bit backwards and we need to pick up and we've got to stay together."
