Rashford has produced some of the best form of his career with Barca during this season's loan from Manchester United.
The England attacker's deal includes a permanent option and he has made it clear he hopes to see Barca trigger the clause.
He told BBC Sport: "I don't feel any pressure. I'm playing football. I feel at home. I'm enjoying every step. It's been a great learning experience. I'm enjoying every little thing, like learning the language, the culture...
"Barcelona was my favorite foreign club since I was a child.
"It's a new way of understanding football. I've always loved Spanish football, and playing for the biggest club is a great honor. I try to play as much as I can and help the team win.
"It's simple. They want us to win. That's what the club demands, and the environment always pushes us to be better. It's a perfect place to play."
