Italian football club Sampdoria have offered Brazil's Internacional five million euros to sign highly-rated left-back Geferson.
But the Genoa-based outfit face competition for the 21-year-old's signature from Serie A rivals Fiorentina, reports Xinhua.
"Internacional haven't ruled out the move but are trying to increase the value of the transfer," a report in Brazilian news service Uol said.
Geferson is a product of Internacional's youth academy and has made 22 first-team appearances for the club since his debut last year. He was rewarded for his consistent form by being called up to Brazil's national squad for the Copa America in June and July.
