Brazil under-20 midfielder Nathan is being sought by Manchester City amid an escalating legal row involving his club Atletico Paranaense, according to the teenager's father.
Jose Carlos de Souza, who also acts as Nathan's agent, told Brazilian sports portal Globoesporte that the Premier League champions were one of eight clubs eyeing the 18-year-old, Xinhua reported Tuesday.
Nathan's contract with Atletico expires in April meaning he is now free to negotiate with other clubs as a free agent.
But the Curitiba-based outfit have taken legal action in a bid to thwart the player's departure.
According to Globoesporte, Nathan has rejected an improved offer to remain at the club.
The playmaker, who has represented Brazil's under-17s and under-20s, has made 13 first-team starts for Atletico this year and scored one goal.
