The Senegal moved sealed a switch to England after moving from German side Hoffenheim to West Ham in January 2011. Despite suffering relegation at Upton Park, the 26-year-old's performances paved the way for a move to Newcastle United in the summer.
Ba has scored 16 league goals for Alan Pardew's side this season, who are now in a strong position to secure European football for next term.
"Since the start of my career my objective was the Premier League. I did everything to reach it," Ba told France Football.
“When I lose I hang my head. I want to go back home because we didn't give fans what they expected.
"There are a lot of players who do not give a damn. Even if I would not do it for the club, I do it for me. I cannot not care!
"What the fans are asking for? Giving your very best. That's the thing the easiest to do. Run, rush, tackle, fight - I can't see anything difficult in that.”
Ba first received a taste of English football after trailing at Watford, and the striker believes increased individual training at Newcastle could improve his form even more.
“I had so much fun when I had a trail at Watford as an 18-year-old. It was the English atmosphere, the way they experience Football. Of course the training sessions are important, but what really matters is that you give everything on Saturday and then people are happy," he said.
"I'd like to have just one training session a day as in England. Not because I am lazy, but because it gives you some time for individual work, on physical level or in front of goal. What I've found in England is total football, where you let go and give your best to win."
