Liverpool may be interested in Araujo as a potential replacement for Crystal Palace captain Marc Guehi, who is a target for the January transfer market.
Suarez, who played with Araujo for Uruguay, has reportedly spoken with his former teammate about the possibility of joining Liverpool.
Barcelona still need to sell a key player in January to resolve their registration issues for the second half of the season.
Araujo was a target for Manchester United and Chelsea last summer.
