The club were awarded the trophy, with Colombian opponents Atletico Nacional given a fair play award.
"We are resorting to a lot of loans," said director of football Rui Costa. "That is a tool for bringing together quality, speed and budget. Many clubs are being partners in this."
Centre-back Neto and full-back Alan Ruschel survived and Costa said they "expect" the two players to come back and wear the shirts. Reserve goalkeeper Jackson Follmann also lived but had to have part of his leg amputated.
"No player this season will use the shirts that were worn by Jackson Follmann, Neto or Alan Ruschel," Costa said.
"More than a tribute, we expect Alan and Neto to come back and wear them. Follmann sadly won't be able to but he will certainly be back here with us in some capacity," he said.
