Ba made the perfect start to his Blues career following his £7.5million move from Newcastle United, scoring twice in the 5-1 FA Cup third round victory at Southampton.
The Senegal striker claims he has already benefited from playing in front of Chelsea's playmakers Juan Mata and Frank Lampard.
Ba said: "I just want to enjoy my football, it's not about pressure, it's about playing a game I like, and that's what I'm doing.
"It makes football look easy, I just try to run in behind and create space for the midfielders because I know when they have space they will be dangerous.
"When you have players like this, that understand football perfectly, you just have to run and the ball will come into your feet, and that's what I tried to do.
"I'm very pleased, I saw it when I played against them, but they are world-class players and when you play with them it's completely different. They create spaces, provide good passes and they are very intelligent in their game."
