Benfica striker Nelson Oliveira is being tracked by Chelsea and Manchester City.

The Daily Mail says the 20-year-old has been on Chelsea's radar since impressing as a substitute for Oscar Cardozo at Stamford Bridge in the Champions' League last April, while City have begun monitoring his form after a clear signal Benfica may have to cash in on him at the end of the season.

Barcelona are also keen admirers, while Real Madrid are aware of a likely scramble to sign him next summer, with Jose Mourinho's agent Jorge Mendes representing him.

Oliveira is currently on a season-long loan at Spanish side Deportivo La Coruna. His Benfica deal runs until 2017 and contains a £24million buy-out clause.
