The former Liverpool midfielder was pushed to the top of Swansea's formation after Alvaro Vasquez - Laudrup's last remaining fit striker - was forced off with a groin injury.
And after Nathan Dyer had broken the deadlock, Shelvey responded in fine fashion by scoring the third goal the game after his presence had forced Mathieu Debuchy into an own goal for the second.
"I think that position suits him [Shelvey] very well," Laudrup beamed.
"He's good in possession, he's good making runs from midfield so I really think that position suits him quite well.
"I think he can play the more dynamic midfielder alongside a holding midfielder.
"In these two games on Sunday and [on Wednesday] we've seen that it suits him very well."Meanwhile, Newcastle boss Alan Pardew criticised the refereeing performance of Howard Webb, insisting two key decisions had gone against his side.
"I didn't think we deserved that," he told reporters. "I was a bit disappointed we didn't keep a clean sheet until half-time, although we didn't retain the ball very well.
"In the second half we pushed on and we created chances.
"Two big decisions have gone against us – [our] first penalty claim was a penalty, I've no doubt about that. I felt it at the time and my players' reactions told me all I needed to know.
"It hit his [Ben Davies'] arm when it was going into the net. That's a penalty, isn't it? He [Webb] said the ball hit him on the arm, but he didn't move his arm towards the ball."
Pardew also questioned the decision not to award a free-kick for a foul on Yoan Gouffran in the build-up to Swansea's second goal.
"That was from a foul on Gouffran," he added. "I thought [Ashley] Williams had no chance of winning that header. He went into the back of Gouff and he [the ref] has played on.
"I accept Webb's explanation but don't agree with it. Then there was an incident with Jonjo [Shelvey], which after looking at the highlights was a bit disappointing for him. You could argue he shouldn't have been on the pitch.
"We had one of those nights where all those things went against us and that impacted on the score."
