Oscar enjoys playing with Brazil pals David Luiz and Ramires at Chelsea.
Chelsea are well placed in the title race.
Oscar told Sambafoot: "Ramires is a really humble guy - a great guy - whom I personally admire a lot. And that's not just on the pitch bit off the pitch too as he's an incredible person. On the pitch there's no need to talk about his fighting spirit - he always gives 100 per cent in every game. I like Ramires and I admire him a lot.
"David Luiz is also a great player. More than anything he's a great guy off the pitch too. He's the person who always gets everyone together here in London - he likes everyone and he helps everyone. He helped me a lot when I arrived here. He's a guy who I admire, too."
