Leeds United are leading the race for Hertha Berlin midfielder Matheus Cunha.
UOL Esporte reports Leeds have intensified their interest in the Brazil international in recent days.
Hertha are prepared to sell and seeking a starting price of €30m.
The club's sporting director Fredi Bobic said: “I am glad that he is with us and that he has no clause.
"Then you have to see whether he will contest the future with us. I can't say at the moment whether he is so happy that he would like to stay here."
