Oscar is convinced Chelsea can dominate Europe.

The young Brazilian says in three years' time Chelsea's young players will be peaking.

"It has been difficult this season because we have been in this period of 'transition'," Oscar told the Guardian. "We've lost some important games, been knocked out of competitions we'd hoped to win, and the Champions League was the biggest one. But we're a young team, a new team, with good players: Eden Hazard, David Luiz, Ryan Bertrand, Juan Mata …These are players who can help Chelsea become one of the greatest teams in Europe again.

"At the moment this is already a big club but, if we have three years playing together as a group, we will prove our quality. It's a question of time. The more games we play together, the more we mature."
