Chelsea midfielder Willian will miss his side's match against Premier League champions Leicester on Saturday following the death of his mother.
The Brazilian, who has been granted compassionate leave, wrote a poem in tribute to her on Instagram on Thursday after her death, reportedly of cancer.
On the club's official website, Chelsea said: "All of us at Chelsea Football Club are sending our love and deepest condolences to Willian and his family after the passing of his mother. We are thinking of you Willian."
Willian, who joined the Londoners from Anzhi Makhachkala in the summer of 2013, scored in Brazil's 2-0 win in Venezuela on Tuesday evening.
Chelsea have won just one of their last four Premier League matches - a 2-0 victory at Hull prior to the international break - but did record a victory over Leicester in the EFL Cup last month.
