Manchester City are reportedly at the head of the queue for Benfica youngster Joao Felix.
City are believed to have met with Benfica president Luis Filipe Vieira last week to discuss a summer move for Felix, who is widely regarded as one of the best young talents in world football.
The 29-year-old - valued at £105m by his Portuguese side - only signed a new contract at the Estadio da Luz in the latter stages of 2018.
However, interest in the teenager has grown following his 20 goals and 11 assists in 43 appearances for the Eagles during the 2018-19 campaign.
According to Marca, Atletico Madrid are firmly in the race as they seek a replacement for Antoine Griezmann but City are 'the leading candidates' for the Portuguese.
Benfica are said to be preparing a offer a huge new contract in a bid to prevent the attacker from leaving the club ahead of the 2019-20 campaign.
