The Premier League outfit are thought to be keen on the midfielder amid reports veteran Frank Lampard is set to leave Stamford Bridge at the end of the season.
The 20-year-old has previously said he intends to stay at current side Atletico Mineiro as long as he feels 'valued' by the Brazilian club.
But he admits 'every player' would like to play at Chelsea.
"We know there is speculation, the press has been talking a lot. But nothing concrete has come so far," he told ESPN Brazil.
"Chelsea are a club with a lot of visibility, they are a club where every player would like to play."
