The 27-year-old Senegalese striker sealed a £7m move to Chelsea last month after scoring 29 goals in 54 appearances for Newcastle since joining from West Ham in 2011.
And Ba, who already has three Chelsea goals to his name, insists he always has full respect for the teams he plays for after opting to move to west London.
“I started in the Premier League in January 2011, with West Ham, who took a chance on me,” Ba told Chelsea magazine.
“I remember Avram Grant was giving me a lot of confidence while I was playing there. Then, I was signed by Newcastle, where I spent 18 really good months.
“I’ve always respected the places where I have played and the shirt that I wear.
“I give my all until the last minute because I play for the club. I respect the shirt and I fight for it. That’s my mentality.
“In the early days, I had a lot of different experiences and a lot of trials that ended up in non-decisions – in France, in England and in other countries.
“I’ve played and had trials in a lot of small teams, but all these experiences have made me what I am today.”
