Per the source, Taffarel advised Lucas to consider moving to the Istanbul giants.
Galatasaray have made the 29-year-old midfielder an offer and club sporting director recently revealed that he would not be surprised to see Lucas join.
Nazifoglu was a guest on Turkish sports radio station Radyospor when he underlined that the deal could go ahead.

The Brazilian keeper won the league title as well as Turkish footballs first European trophy – 2000 UEFA Cup – during his time playing for the club.
Taffarel also played a major role in Brazil winning the 1994 World Cup in the US.
