Jay Saunders accused Maidstone players of accepting defeat and has promised to make changes after their collapse against Woking.
Saunders was happy with Stones’ start against a Cards side who turned up at the Gallagher without an away win.
But they fell apart after conceding twice in four minutes around the half-hour mark and the manager is running out of patience after a 3-0 defeat.

Saunders, whose team remain 17th in the National League, said: “I don’t know how much it hurts some of them in there, and I just said that to them.
“Changes have got to be made and sooner rather than later.
“There’s players we like and if people have got to move out, that’s what we’ll do because I won’t accept it. I can’t accept it. It’s the most disappointed I’ve felt in six years as manager here.”
Saunders added: “I think they know I’m right, and that’s the thing.
“As a player, I’d have lost my head and gone through and smashed someone, and I look at them and they’re letting things happen.
“That’s the difference. It would have hurt me as a player, it hurts me as a manager, and I just don’t think some of them understand that.
“Whether they thought Woking would be an easy one because they’re lower in the league, I don’t know.
“I thought personally for half-hour, 25 minutes, we were very good, we started the game really well and they couldn’t get near us but the first attack, it’s a goal and that’s us.
“We’re too weak and then mentally I think we just go a little bit.”
Stones are six points above the bottom four and Saunders wants players who are willing to fight to keep them out of trouble.
He said: “We’ll have to get some out first and that’s what we’ll do because I shouldn’t have to keep changing the team week in, week out.
“Two of them were forced today (Seth Twumasi away on business and Anthony Acheampong out with a hamstring injury) but I look in other areas and I’m having to change personnel all the time just because people aren’t earning their shirts.
“At the end of the day, if people earn their shirts, they keep them. At the moment, three or four are earning their shirts, the rest of them I could toss a coin on most positions.
“It’s never easy but I’d rather get players with maybe a little less ability but I know what I’m going to get out of them every week.
“I’ve got some players with good ability here, no doubt about it, but I need six and sevens out of 10 every week, not an eight here and there and then a four because it’s no good to me.”
