The Senegal striker netted a hat-trick as the Magpies won 3-1 to go third on the Premier League table but was the subject of some negative behavior from Potters fans after his failed signing in the summer.
Stoke were extremely close to bringing Ba to the club from West Ham United but a deal fell over and in the end he landed at St James’ Park on a free transfer which has proved a bargain buy as he has now scored eight goals in nine appearances.
“I can’t go back to the past. If they want to boo somebody they have to boo their board because I was there to sign and they didn’t want to sign me,” he told Sky Sports 1.
“So today I’m very happy to score a hat-trick there because it’s a place where you struggle to have a win and today we were terrific as a team.”
And Ba said it was vital that the likes of himself and Leon Best did what they could to help out the Magpies defence who were bombarded by Stoke’s usual aerial threat.
“It’s very important when you have strikers who can run and defend and it releases the midfield and today the team at the back were very strong,” he added.
