Galatasaray have entered talks with Tottenham target Bruma over a contract extension a source close to the player told Turkish-Football.
The Lions have offered Bruma a three-year deal which will see his current €1.2m salary double.
Bruma still has another one-and-a-half years remaining on his contract but Galatasaray are worried that they may lose him for less than their valuation.
Tottenham have been scouting Bruma this season and have expressed an interest.
Bruma is a Tottenham target and has other Premier League sides have been keeping tabs.
Galatasaray want to keep hold of Bruma until at least the end of the season and include a €30 million release clause into his new contract.
Bruma’s agent is currently locked in talks with the Istanbul giants and negotiations have reached an advanced stage.
The Portugal international has been in great form for Galatasaray this season scoring five times and providing five assists in 16 league games.
Bruma joined the Lions from Sporting Lisbon in 2013 on a €10 million move as one of the brightest talents of his generation.
The 22-year-old struggled in his first two seasons due to injuries and regular managerial changes which disrupted the team.
The young winger was loaned out to Real Sociedad last season before hitting the ground running on his return to Galatasaray.
Bruma has managed to stay injury free for over a season now started showing why he was so highly rated as a youngster.
Galatasaray signed Garry Rodrigues from PAOK on Tuesday and his arrival was taken as a signal that Bruma could be on the move by sections of the Turkish press.
Rodrigues could however, end up as cover for Lukas Podolski who is close to securing a big money move to the Chinese Super League.
Galatasaray went into the winter break in third place just three points behind league leaders Basaksehir.
The Istanbul giants have been able to focus fully on the league this season due to being suspended from European competition due to breaching FFP regulations.
Galatasaray are not in a position to turn down an offer that matches their valuation and will listen to offers over the summer but the club does not want to lose a key asset mid-way through the title race.
