The Magpies spent much of the 2012/13 campaign punching below their weight in the bottom half of the table.
A reversal in fortune has seen them position themselves back in the European-chasing pack this term, with a 27-point haul good enough for sixth spot.
They improved their tally by one over the weekend after holding Southampton to a 1-1 draw at St James' Park and Krul believes they displayed the kind of battling qualities during that contest which will serve them well heading forward.
He told the Evening Chronicle: "It was a good point, it keeps Southampton at a distance.
"Last year we would have lost these type of games so I am pleased we took a point in the end.
"Both sides had their chances. We had two good chances and they hit the post.
"They had their chances as well and Adam Lallana made the difference when he came on. It could have gone either way."
Newcastle have now taken four points from their last two outings - against Manchester United and Southampton - and Krul feels that is a positive return heading into the busy festive period.
The Dutch shot-stopper added: "Now we have Crystal Palace away and it is a difficult game.
"It is also a game we look forward to and we go there with a lot of confidence.
"You cannot win every game so I am pleased with a point."
