Nelson Jardim believes Newport County’s improved defensive record can be attributed to his squad’s grafting since he arrived at the club in the summer.
The Exiles kept just one clean sheet in their opening 12 League Two matches of the season.
But they head to Wimbledon on Tuesday night (19:45 GMT) having shut out their opponents in four of their previous five league matches – with only Tranmere Rovers scoring a League Two goal against Newport in that period.
And following what was a major overhaul at Rodney Parade over the summer, Jardim feels his side are now starting to benefit from having had more time together on the training ground.
“With all of these changes, there were a lot of things we had to work on,” said Jardim.
“But that shows we’ve improved on that side of the game.
“We know that invincibility lies on the way that you defend. If you defend well you are hard to beat, we’re trying to do that.
“That is down to the work that we’ve been doing and the effort that everyone is putting in.”
