The Senegalese ace has struggled to make a huge impact since joining from Newcastle United last month and with suggestions that the Blues could make some additions in the summer, you could forgive him for being worried.
However, Ba says he would welcome any new strike signings and has assured that he will work even harder to force his way into the first team at Stamford Bridge.
"I am at one of the biggest clubs in Europe and each year, they're going to bring in a forward,” he told radio station RMS.
"But that is part of football and that is what makes me a better player if you go about things the right way.
"I am always working hard and I know that I can achieve great things. If they buy a new striker, it'll help me improve. But I won't let anybody walk all over me."
