Mane remembered his former teammate with an Instagram story showing the pair celebrating a goal against Manchester City, accompanied by broken heart and sad face emojis.
Fabinho expressed his disbelief and sadness with a picture of a goal celebration hug, writing: "There are no words to describe this sad day. It is still hard to believe that this happened. I had the privilege of having lived with this incredible person, Diogo. He will be missed, brother! May God comfort the hearts of Rute, the whole family and all those who loved Diogo and André. May they rest in peace. RIP".
Naby Keita posted two images, one in training and another during a match, captioned: "I will never forget you bro. Shocked by this news. RIP Diogo”.
Xherdan Shaqiri also joined the chorus of tributes, sharing a goal celebration photo and writing simply: "RIP Brother.”
And Harvey Elliot added:
"Diogo, I can't believe you've gone. It's hard to put into words how much this hurts us. You were an incredible footballer...the kind that made a difference every single time you stepped on the field. You were humble, hardworking, kind and always there for anyone that needed anything.
"I feel so lucky to have shared the pitch with you, shared memories and moments I'll carry with me forever. You'll always be part of this team, part of the Liverpool family. We will never, ever forget you. My heart goes out to your whole family. Love you brother. Rest easy Diogo and Andre. You'll Never Walk Alone."
