The Spanish champions have been linked with summer moves for the two attackers to augment a forward line that includes the ageing Uruguayan and an out-of-sorts Antoine Griezmann.
Neymar previously enjoyed a four-year spell at Barcelona, forming a lethal attacking partnership with Lionel Messi and Suarez before departing controversially for Paris Saint Germain in a world record deal three years ago.
The 28-year-old Brazilian tried and ultimately failed to engineer a return to Barcelona last season but senior figures at the club are still interested in bringing him back.
Martinez has been linked with a move to the Camp Nou in recent weeks after enjoying his best run of form at the San Siro since moving to Italy last season, with 16 goals across all competitions for Antonio Conte’s men.
"It is difficult to talk about players today," Suarez told Mundo Deportivo.
"As is the situation in the world today, talking about who can come because of how everything is complicated. But I can speak about what these players are like and they are huge players.
"Obviously, Ney, everyone knows him and we know the appreciation that we have for him in the dressing room, which as a player is indisputable because he still has a lot to give and in the dressing room he would always be welcome because of the affection he has.
"Lautaro is a player who has been growing a lot in Italy, he is a 'nine' who has movements that are spectacular and that reflects how great a striker he is.
"It is not that you feel compatible but that you feel happy that the club wants to incorporate players who come to help and fulfil the same objective of everyone - that of wanting to win everything.
"Then when it comes to healthy competition in the team, which there will always, we will always be on the same side.
"So players who come to fight for a place and help the team will always be welcome, it will always be better and it will strengthen the group."
