Plymouth Argyle manager John Sheridan has hit out at his side for playing "like it was a testimonial" in parts of their 2-0 defeat away at Carlisle.
The Pilgrims have won just three of their last 12 matches in League Two as they head towards the season's finale.
"The way we played, it was like a testimonial," Sheridan told BBC Devon.
"We've done everything we can because we knew we wanted to be fresh, but we've probably given our most lethargic performance of the season."
Sheridan's team remain seventh but are level on points with Luton Town and only in the play-offs on goal difference.
They welcome bottom of the table Tranmere to Home Park next and will have to get something at Shrewsbury to secure their play-off spot.
"I'm not a light switch and neither are the players - you can't just turn on and off whenever you want," Sheridan added.
"I don't know if some of us think football 100% of the time like I did and most good footballers do."
"You can't just give a performance one week and then I don't see you for two or three weeks."
"People have got to look at themselves, me included - I stuck with the same team so I've obviously picked the wrong team haven't I."
