A Demba Ba brace snapped Newcastle United's five match winless streak in the Premier League and left the Magpies sweating over the striker's future.
Ba opened the scoring with a penalty before firing in a second to give Newcastle a 2-0 lead over Wigan at half-time.
The club will be looking to quickly ratify an escape clause in the Senegalese international's contract after his strong performance and Alan Pardew is eager to hang on to the talisman.
"The truth of it is that Demba has got a clause in his contract and it is still hanging over us," Pardew said. "We have tried to negotiate away and we have not managed to do that as yet.
"But the one thing I will say on a positive note is that he has never, if I am honest, looked me in the eye and looked like he wanted to do anything else but stay here, and I hope he does."
The win was Newcastle's first since their 2-1 win over West Brom in October and Pardew believes it will be critical for confidence on Tyneside.
"It was a massive victory for us, and I am very proud of my staff and my players because we have had to stand tall," he said. "Four defeats in this city isn't easy for any team, I don't think. There was a lot of pressure on us."
Wigan manager Roberto Martinez revealed the Latics would consider appealing Maynor Figueroa's red card after he his foul on Papiss Cisse handed Newcastle the elad.
"You need to understand, Maynor is as honest as you are going to get," Martinez said. "He is one of the most honest footballers I have ever worked with.
"When he makes a rash challenge, or if he makes a challenge he feels is clearly breaking the law, he will accept responsibility.
"He was destroyed. He was very, very upset at half-time. All he was saying was, 'I challenged, I went shoulder-to-shoulder and the ball was there to be won'.
"If you look at the replay, that's exactly what it was, so I do feel for my player. He didn't do much wrong.
"It's a decision that really changes the dynamics of the game, but then to concede from a penalty is clearly a double punishment."
