Martin Smith said the players have to take responsibility for lapses in concentration, after Town were beaten 1-0 at Colchester United.
The game, as a whole, was lacking in real chances for either side but the U’s were ruthless scoring with one of very few clear-cut opportunities.
Sammie Szmodics was the man that got the goal for the U’s moments after former-Town striker Luke Norris had been stretchered off.
Smith said the players have to stay switched on at key moments in the game, as this was the second week in a row Swindon had conceded on the stroke of half-time.
“The way I see it is that, as individuals on the pitch, we have to take responsibility. That’s the only way – it doesn’t come with coaching or nothing like that, it comes from us, ourselves.
“We have to realise in key moments of the game: i.e, beginnings and ends of halves – that we have to switch on and be streetwise. We have to be ready from restarts, set plays and we have to get to grips with that really quick.
“We’re shooting ourselves in the foot at the minute.”
Despite the loss, Smith believes that there was little to separate the two sides.
“There was nothing in it. It was a tight game and we cancelled each other out.
“There weren’t many saves, there weren’t many shots and there weren’t many chances. I think the game was going to be won with a bit of magic or a mistake.
“We got to 45 minutes, Luke Norris went down with an injury and then we’ve switched off as a collective, as a team.
“The lads are devastated with just the way we conceded the goal.
“Then in the second half, we got out and tried to do what we did in the second half last week against Notts County.
“We took the game to them. We were positive and we dominated the second half, we just couldn’t get that goal.”
The midfielder was one Town player who almost provided the catalyst for a comeback, including one fantastic chance to level the game, but Rene Gilmarten made a top save to put a stop to those hopes.
“I’ve got to score. I’ve got to put the ball in the net because it is a great chance.
“I got in with a one-two with Keshi and I have to put it into the back of the net because in games like that, there is nothing in them.”
