Oscar netted two goals in a week following his strike at Stamford Bridge on Saturday, whilst Willian had his largest impact of the season - assisting his kinsman before rounding off the victory over Aston Villa with his first goal of the campaign.
However, their performances at the opening of the campaign were less prominent, with both Brazilian internationals apparently jaded in the wake of the World Cup over the summer. The host country reached the semi-finals of the tournament, before an embarrassing defeat to Germany weighed heavy on their bodies - as well as their minds.
23-year-old Oscar has come under the full strain of over-exertion, with his Chelsea career interjected with appearances at both the World Cup, but also the Confederations Cup in 2013 - leaving the youngster with no extended break in almost two-years of football.
To compensate for the late World Cup finish, and the lack of holiday, the Brazilian’s were given time off during the pre-season, and Blues head coach Jose Mourinho is glad that they are started to get back into the ‘intensity’ of the game.
Speaking to the official Chelsea website, the Portuguese coach said: "Willian didn't start the season well. Everyone that came from the Brazil national team without a proper holiday had enough time in the pre-season to start the season in a very strong way.
"Now they are getting into the intensity of the game.
"Players need holidays and a proper pre-season.”
Willian played less frequently for both Chelsea and Brazil last season, and so has started the season as a more regular fixture in the Blues first-team, making five Premier League appearances to Oscar’s four. Despite the younger midfielder netting twice in a week, his performances still appear laboured, and his effectiveness has reduced from his early career in West London.
However, with the number of attacking players on the Blues books, Oscar may be afforded a longer holiday in the coming weeks, allowing him to return to the player that lit up Stamford Bridge during his first season in the Premier League.
