Shaw believes they played right on the edge through the 90 minutes.
"It was massive, I think we spoke a lot about the game and before the game about winning, that was the most important thing today," Shaw told Sky Sports following our victory.
"It was making sure that we win and getting the three points. I think, in the second half, you could see how desperately we wanted to win and get the three points.
"We kind of just sat back and took a lot of pressure from them. But, you know, I think the lads and the whole team defended well. We're really happy with the three points."
Asked about upping the aggression levels, Shaw continued: "Yeah, I think so.
"We started the game really well, really sharp, really physical. We put them under a lot of pressure in the first five and 10 minutes and obviously that then brings the mistake from them.
"We know we can punish teams more with the chances we've created but, definitely defensively, we were much better defending in the box. We're very pleased."
