His perfect treble at the Britannia Stadium was accompanied by a chorus of jeers, but the Senegalese striker then told Potters fans to aim their anger closer to home
The Senegalese forward was jeered from the start after his move to Stoke in January fell through amid reports of him failing a medical. The striker, who went on to sign for West Ham instead before joining the Geordies this summer, was bullish in blaming the Potters' directors for the transfer breaking down.
"If [the fans] want to boo somebody they have to boo their board, because they didn't want to sign me," Ba told Sky Sports, who was clearly delighted with his second hat-trick for the club. "Today I'm very happy to score a hat-trick there because it's a place where when you come you struggle to win... and today we were terrific as a team."
When quizzed on Newcastle's defense, still the tightest in the league, Ba praised the way that his side press from the front.
"It's very important when you have strikers who can run and defend, and today with Besty [Leon Best] we did our best for the team, and at the back we were very strong."
Despite his Halloween heroics, he was forced to share the man of the match award with Argentine midfielder Jonas Gutierrez, who shared his views on an excellent team ethic from the North-Eastern club.
"I think all the team worked hard in defence, it was a hard game, the whole team had to defend well; at free kicks, at corners, at throw-ins. Not just me, all the team were really good," Gutierrez added.
The winger was quick to point out the importance of this result too, but played down talk of qualifying for a Champions League spot, despite leapfrogging Chelsea into third spot.
"Not all the teams that come here take something and we won," he continued. "The pitch is small, they are really good with set plays, so this is one of the best [results] in [the league]. All the games in the Premier League are tough, so we need to focus on the next game and at the end of the season we will see where we are."
