The Senegal international reveals that he loved his time at St James' Park but says he returns to the North East focused only on earning another three points for Chelsea
The 27-year-old made the move to Stamford Bridge in January and returns to St James' Park for the first time on Saturday.
The striker is aware he may recieve a hostile reception from the Magpies' supporters but insists he won't let the occasion get the better of him.
"Newcastle is going to be a big game for me but I won’t let the occasion go overboard," Ba told The Mirror.
"Whenever you join a club you look at the schedule to see when you can play the team you left. So I knew straight away it would be coming fast for me to go back to St James’ Park.
"But that’s not the most important thing. At the end of the day, it’s only another game, three points, nothing more than that."
With 29 goals from 57 appearances, Ba says he is proud of what he was able to achieve during his Newcastle career and wants to thank the fans for their support.
"I’m proud of what I did there, of course I am," he said.
"I did some good things there, no question about that, and from the first day to the last one I gave everything.
"The fans gave me 100 per cent from day one to the last day but I gave them the same back.
"But this is life in football, from one day to another you can exchange and it is part of the job.
"Now I am at Chelsea, the next level. When you play, it’s to win, to win trophies. That is what it is all about and what is in my mind."
