Telles is nearing a move to Premier League champions Chelsea according to Sky Italia reporter Gianluca Di Marzio.
Fanatik report that French giants PSG have also been closely linked with the 22-year-old full-back however, his agent Fernando Otto revealed that no formal bids have been made.
“I have not received any offer. He is happy in Istanbul, he loves the city and so do his family but in football you never know what can happen, maybe some clubs have made contact but not in an official capacity,” Otto told Radyospor.
Telles joined Galatasaray on a €6 million transfer from Gremio last January and still has another three-years left on his current deal.
The Brazilian fullback was part of the Galatasaray side that won the league title for a record 20th time last season. The Lions also won the double and earned the right to wear a fourth star on their shirt next season.
Telles provided a total of two goals and three assists in 56 games for the Lions last season.
