Massa told Spain's AS newspaper that the uncompetitive 2020 Ferrari is not Vettel's fault.
"The car is the most important," said the Brazilian. "Without a competitive car you cannot win and that is not about the drivers.
"On the other hand, I think Sebastian's moment is over. He's not doing the job one expects from a four-time world champion and I think the team is right to make a change.
"He thinks that he is not being treated well and for the team it is not good to have a driver in this situation, without being competitive," he added.
"I think his departure was the best solution for both of them."
