"Sadio is talking to me all the time. He advises me to 'do this, do that'. He is a big brother for me," said Sarr to BBC Sport.
"When I arrived, he sent messages saying welcome to the Premier League, welcome to England and we also talk when we are in the national team.
"He gives me tips, I try to execute them and to implement them. 'If you don't play, be calm, carry on, do your job, it will be OK', that is what he says. So I try to do the same.
"If I do not play, no problem. I come and work on the following day."
He added: "I think the match will be like any other. We are going to work. We are going there to fight. We are not going there just to watch Sadio play - we will also have to play.
"I have to show I understood the advice I was given by him. At the end of the match he can give me some more tips."
