Grêmio have sacked Caio Júnior after just eight games in charge, with former Seleção coach Vanderlei Luxemburgo the favourite to succeed.
Júnior replaced Celso Roth in the Olímpico Monumental hotseat in December and, following heavy investment by the club hierarchy, was expected to deliver Copa Libertadores football next season.
Following Sunday's shock 2-1 defeat to minnows EC São José - his third Taça Piratini loss to lower oppostion - the Gremio board of directors finally lost patience with the 46-year-old.
Assistant-coach Roger Machado takes over in the interim, starting with Wednesday's Gre-Nal derby against bitter rivals Internacional at the Beira-Rio.
Vanderlei Luxemburgo, recently sacked by Flamego due to his strained relationship with Ronaldinho, is expected to be appointed Júnior's successor later this evening.
