Roma coach Eusebio di Francesco says they must keep hold of Alisson Becker.
Alisson, a target for Liverpool and Real Madrid, kept a clean sheet for victory over Crotone.
Di Francesco stated: "Real Madrid wants Alisson? I'm very calm, we do not have to talk about the market in March because we have important games.
"It is obvious that such a player is well liked, but we have to think big.
"We must start holding onto some players."
