"We are top of the league until Monday. It is good to be there, it gives you a lot of confidence," the Brazil midfielder told LFC TV.
"We just go game by game. We know our main target is to play Champions League again and every week we are improving.

"We go into the next two games knowing they are crucial but with a lot of confidence, especially after winning four games in a row."
