JUSTIN Edinburgh insists Grimsby Town will "smell" any complacency from his side on Sunday – and take advantage of it.
The Newport County manager was understandably delighted with his side's last-gasp play-off first leg victory at Blundell Park.
But the former Spurs full-back is taking nothing for granted ahead of Sunday's semi-final second leg in South Wales.
He said: "We were excellent – disciplined, dogged, resolute – all the things you need to come to place like Grimsby with a fantastic home record.
"We started ever so well, we looked bright and took the game to Grimsby but slowly, but surely, they got back into the game and pressed us back in the second half.
"We knew that if we could keep a clean sheet that would stand us in good stead going into Sunday's game.
"As we saw on Wednesday, there is nothing between the two teams and we're going to have to be as good, if not better, to progress.
"If we feel any complacency, Grimsby will smell that and take advantage.
"It was a good atmosphere, very hostile, but I think we will have exactly the same at Rodney Parade on Sunday and I'm sure that our fans will spur us on."
