The two clubs are locked in transfer talks over a deal for Lautaro.
Setien said, “We're all clear there are four or five footballers who play in his position who are extraordinary and that any of them have what it takes to play for Barcelona.
“In reference to this player, he's a player who can be very good in this team, as well as the others who may be at his level."
Setien also has no problem with Arthur Melo declaring he wants to stay.
“If he's said that… I really have nothing to say about the future of the players. I'm very focused on what lies ahead, on our work.
“I'm going to need all my players because we don't know the circumstances and how they'll developed once the competition resume.
“There's a long way to go, we can't be speculating on these things. I'm counting on everyone and I hope everyone is able to perform at their best in the 11 games that remain."
