The Spanish professional - who played as centre-back for Real Madrid before transferring to PSG last year, alongside Lionel Messi - is yet to live up to his reputation due to injury problems.
Ramos has been limited to 10 games across all competitions due to injury but says he wants to make an impact with the French giants.
Ramos said in a video produced by PSG: "I've spent [too] few hours on the pitch this season in the PSG jersey,
"I'm at the prime of my career and eager to show my new team, Paris Saint-Germain, how much football I have inside me. [My big goal celebration in the 3-0 win at Angers] was a reflection of the sacrifice I've had to make."
The 36-year-old footballer, reflected on the difficulties he was faced with such as home sickness when moving across to France after spending more than a decade with Real.
He added: "At first it was hard to adapt, I had been with another club many years, where you had everything under control, the club, the house, the children's school. It was not so easy to get to a city as spectacular as Paris. It was difficult for us to find a home.
"With respect to the team, it was fast to adapt because I knew some players, like Keylor Navas. We had an extraordinary and unique rapport at Real Madrid and to have coincided here with him has made everything so much easier. It is good to change, to value what you've experienced and what you know. You get a broader view."
