Former Barcelona and Inter forward Samuel Eto'o praised Lautaro Martinez, but said Luis Suarez deserved more respect for his contributions.
Martinez, 22, has been heavily linked with a move to the LaLiga giants, with the Inter forward regarded as a long-term replacement for Suarez.
Now 33, Suarez arrived at Camp Nou from Liverpool in 2014, and has won four LaLiga titles and a Champions League with the club.
Eto'o, who spent five seasons at Barca and two at Inter during his playing career, said while Martinez was talented, Suarez's efforts could not be ignored.
"I love Suarez, he's one of the best in the world in his position," the former Cameroon international told Catalunya Radio on Wednesday.
"Barca always have to strengthen, but they don't need to stand down a general like Luis Suarez. In his position, he's a general and you cannot compare him with anyone.
"Lautaro is doing really well with Inter and has a future, but people have a tendency to forget recent history and Luis is writing history, not just at Barca, but in football. That has to be recognised.
"That doesn't impede bringing in another player to add competition to the group, knowing how many games Barca have, but a little respect for those that have written history."
Suarez had scored 14 goals and provided 10 assists in 23 games before this season was suspended due to the coronavirus pandemic.
Martinez, meanwhile, had 16 goals in 31 games for Inter, while providing two assists.
