Scarborough boss Nick Henry accused his side of going through the motions in their 1-0 home defeat by Southport.
Henry said: "Some of our lads thought they could just turn up and play.
"But credit to Southport, they worked hard which is what all good teams do, even Chelsea and this is a big wake-up call for some of our players.
"I think that this has been coming for a while, and it proves that perhaps we're just not good enough, and it's not good enough."
