Manchester City and Chelsea have reportedly joined the chase to sign Benfica striker Nelson Oliveira.
The 20-year-old, who is understood to have a £24m buy-out clause in his contract, is currently on a season-long loan at Spanish side Deportivo La Coruna.
Barcelona and Real Madrid have also been linked with a move for the Portuguese international, according to the Daily Mail.
Oliveira made four substitute appearances for Portugal at Euro 2012 before the team went out in the semi-finals to eventual winners Spain.
