Chelsea interim boss Calum McFarlane has confirmed that Brazilian winger Estevao will miss the remainder of the English season and could be out of the World Cup after suffering a hamstring injury.
Chelsea hope to have Estevao and Reece James fit as they face a challenging task returning to winning ways in the Premier League against Arsenal at the Emirates Stadium this weekend.
Estevao Willian has said the hard work he has put in behind the scenes at Chelsea paid off after his stunning solo goal set the tone for a 3-1 Premier League win over Crystal Palace at Selhurst Park on Sunday.
Chelsea have been handed a fresh injury concern ahead of their Premier League trip to Newcastle United on Saturday, with Enzo Maresca confirming that winger Estevao is set to miss the match.
Chelsea's 18-year-old winger Estevao produced an impressive cameo performance off the bench in a 3-0 Premier League victory over Wolves on Saturday, earning praise from manager Enzo Maresca.
Chelsea boss Enzo Maresca believes teenage winger Estevao is "destined to reach the top of football" and could one day compete for the Ballon d'Or.
