Ba, who was rejected by Stoke City was on target again on Sunday when he was in the side that lost 2-1 to Manchester City.
The defeat at Eastlands made it five in a row for the Hammers, but Ba reckons they only need the tree remaining games to save themselves even though they are rooted to the bottom of the table with just 32 points.
Ba said: “I see how the players train. I see how they react after games and I cansay that we are going to fight to the end. It is a great team to play in. We are going to keep our cool, put our heads down and keep on working.
'In the last three games we have to give everything, not just tactically.
'It is not only about tactics but it is about fighting.
'We are playing teams around us in the table which will help us. I think if we beat them then we have more chance to stay up.”
