"This is a big step in my career," Sandro said in a statement. "Everton is the ideal club for me, I've got the ideal manager who is going to keep giving me the confidence to improve my game."
"It's a big jump in my career coming to the Premier League and for a club like Everton which is really on the up.
"They have got big plans and want to succeed and keep developing."
Everton have been one of the busiest clubs in the transfer window, having signed goalkeeper Jordan Pickford from Sunderland and Ajax captain Davy Klaassen.
Nigeria striker Henry Onyekuru also arrived from KAS Eupen but will be spending the next season on loan at Anderlecht.
