Whitley Bay manager Paddy Atkinson was frustrated by yet another injury to one of his defenders as his side lost 2-1 at Sunderland RCA on Saturday.
The boss was also critical of the lack of communication between players at key moments in the game.
“Yet again we lost a centre half [Chris Reid] to injury and it was after less than 15 minutes and it totally disrupts the shape,” he said.
“It’s happened time and time again and you wonder how many more times it can happen. We can’t keep losing players every game.
“It was always going to be a tough game on a sloping pitch.
“When you look at the way we played it was probably one of the better games we’ve played in a long time, but then just two mistakes cost us.
“If we can get our full, strongest team out we’ve got a chance, but with repeated injuries and then we’d got Steve Gibson away at a wedding, we’re having to rely on lads who aren’t what you’d class as first team regulars, so you’re always risking a slip up with a mistake somewhere.
“We’ve got to be on top of our game every week. We didn’t deal with their set play properly.”
And Atkinson was critical of the way his side conceded both goals.
He said: “Marking wasn’t tight for either goal, at the free kick and throw-in.
“I keep saying to them ‘you need to be louder on the pitch, it costs you nothing to shout, communication needs to be better’.
“I don’t want to take anything away from Dan [Gladstone] because he’s been great over the last few weeks, but he could have done better with the first goal, organised his defence for the free kick and punched clear.
“It’s a lack of continuity and experience and we can’t just keep on changing the team week in week out and that’s what’s disappointed me today.
“They didn’t hurt us, all they did was lump the ball down the slope, we totally outplayed them and we’ve come away with nothing, that’s what’s frustrating for me.”
