Asked if it was his best performance yet for Newcastle, Ba replied: "I don't know if it's my best because I have had a couple of good ones.
"But this one, to be fair, I am proud of because we were playing the champions.
"We won 3-0 at home and when you have a good performance like that, it's just unbelievable.
"I will look forward to playing in Africa. I am going to work hard there so I come back still being fit and still being able to score some goals.
"If we stay in a high position until we come back, that will be great."
