Steve McKimm described Tonbridge’s performance against Slough as absolutely diabolical.
McKimm was an angry man at full-time after Angels slumped to a 1-0 home defeat in the Good Friday sunshine.
Victory would have seen them all-but safe in National League South going into Monday’s game at Dulwich.
And while they still have an eight-point cushion over the bottom team, which is now Billericay after Welling fought back from 3-0 down to draw at Eastbourne, that was of little consolation.
“It was an absolutely diabolical performance, from start to finish,” said Angels boss McKimm.
“We had no energy, no guile, no real urgency, and in the position we’re in we can’t afford to do that.
“Slough have had two or three shots, and we’ve had two in 90 minutes, which at home isn’t good enough.
“All in all, we were nowhere near the levels we need to be at.
“We are fighting a relegation battle, which I’ve said for ages and I’ll keep saying, because teams around us will win.
“Look at Welling today, 3-0 down at Eastbourne and they end up 3-3, so they aren’t going to give up the ghost.”
The only goal came four minutes into the second half with Joe Dandy allowed to run into the box unchallenged before setting up Alfonso Tenconi.
“We’ve let a player run past four of our players without putting a challenge in,” added McKimm.
“That says it all. I am angry. It’s disgusting.
“We’re in a position where we can’t afford to turn in performances like that, so there’s a lot of changes that need to be made come the end of the season and there’s a lot of changes that need to be made against Dulwich.
“There will be changes and there needs to be changes.
“I didn’t ask for explanations in there, I just told them what I thought, and that was it.
“I can’t blame the heat. Slough could run, they ran further than us today.
“I’m not one for that but if you check their stats and check our stats, they ran further than us with and without the ball.
“So we’re chasing shadows but when we had the chance to get on the ball, we didn’t get on the ball properly.
“That’s what matters - bravery.”
McKimm, who lost Tommy Wood (ankle) and Craig Braham-Barrett (back spasm) at half-time against Slough, is hoping to have on-loan Crystal Palace midfielder James Taylor available at Dulwich after missing the last couple of games with concussion.
Asked how many changes he could make, the manager said: “Well, there were five on the bench today who could come in, it just depends on what I’ve got available in terms of if any of them got knocks, other than Woody and Craig.
“James Taylor, I’m hoping he will be back but again we’ve got to wait for Palace to give him the go-ahead. I’m not sure if they will.
“It’s taken a bit longer than normal but they’re a professional football club that do rigorous tests and he still isn’t right.
“We need a positive result at Dulwich. We need a draw or we need a win.
“We can’t lose again because we will drop deeper and deeper into it with less games to go.
“Today was a perfect opportunity for us to give another bit of space between ourselves and the bottom, and then you look at the game on a Monday and a point might have done you.”
