The Senegal striker, who signed from Newcastle in January, scored his fourth Blues goal in Saturday's 1-0 Barclays Premier League win against West Brom which helped to consolidate his side's position in the top four.
Attention turns to knockout football this week, with Sunday's FA Cup quarter-final at Manchester United either side of the Europa League last-16 two-legged tie with Steaua Bucharest.
Ba told Chelsea TV: "Every point is important now and we are going to approach all the games we have left the same way, to try to win them and try to finish in the top three.
"There is a lot of quality in the squad and in the Europa League I know we can go to the end.
"The FA Cup is going to be tough next Sunday against Manchester United but with 11 men against 11 men anything can happen."
Ba, who is ineligible in Europe having already represented Newcastle, has been rotated with Fernando Torres up front.
He added: "I have settled in very well and you can see it on the pitch I think. Within this team the players are brilliant and they make me feel comfortable.
"It has changed a bit for me because at Newcastle I was more a `nine-and-a-half', and here I am really playing as the `number nine', and I play with three brilliant players just behind me. It has changed a little but I adapt."
