Chelsea attacker Eden Hazard said he and Diego Costa had dedicated their goals in the 3-0 victory over Leicester City to Willian after the death of the Brazil international's mother.
Costa and Hazard both made "W" symbols with their fingers after scoring in tribute to Willian, who has returned to Brazil following the news.
"It's for Willi, Willian," he told Sky Sports. "He's back in Brazil. He lost his mother. We are thinking about him. I hope he comes back stronger."
Chelsea wore black armbands as a mark of respect and boss Antonio Conte told his postmatch news conference: "I want to dedicate the performance, the win, to Willi and his family.
"It's a sad moment for him but he must know that it is also [bad] for us, because we are very close to him and his family."
Meanwhile, Hazard has said he is enjoying playing in Conte's new 3-4-3 formation, which mirrors the tactics used by Belgium boss Roberto Martinez.
"I play more inside the pitch," he said. "I don't stay wide. We play also this system in the national team for Martinez. I think we have more freedom even when we lose the ball, we can get the ball back. It's a good system for Chelsea."
Greattt team performance today congrats to the lads �� all our thoughts and prayers go to @willianborges88 stay strong ���� #KTBFFH

N'Golo Kante, meanwhile, was named man of the match in the victory over his former club.
