Magpies manager Alan Pardew has criticised the 27-year-old's agents for "misrepresenting" the striker amidst his failure to sign a new deal and interest from the Blues.
But the striker, who has scored 13 goals in 20 Premier League appearances this term, insists he is not motivated by financial gain thanks to his Islamic faith.

"I look after myself and my family but I won’t forget people who struggle. My father lives in Senegal. They are from the smaller villages and know how to distribute money to people who need it.
"People sometimes have a bad image of Islam but that is an image of what people are doing with Islam. It gives me so much."
The Senegal international went on to recall a period following his initial move to England in which he had so little money that he struggled to buy food.
"In those days, we were eating only crisps and drinking water. We had no money but we had a lot of fun," he continued.
"We were just having a good laugh in the African style. It doesn't matter what you have, as long as you're happy with the people you are with."
Ba also spoke of the "gamble" he took in joining West Ham on a deal which could have been terminated at any time due to his battle with a knee injury.
He continued: "West Ham inserted a clause that they could terminate my contract if I did not play a certain number of matches that season.
"I said to myself, 'Take the gamble man, you've come from nowhere. If you go back to nowhere, it’s no problem.'"
