Oscar: Wanted by Chelsea and Tottenham

The European champions have been chasing the playmaker for several months, while Tottenham also wanted the 20-year-old.

Chelsea were said to have failed in a previous £20m bid for Oscar, but Sky Sports News understands the Blues have succeeded with an improved offer.

A transfer could now be finalised, despite the playmaker's agent having previously claimed a move to Stamford Bridge was looking increasingly uncertain.

Oscar is expected to arrive in the United Kingdom on Tuesday with the Brazilian Olympic team.

The youngster, capped six times for his country, is regarded as one of the best young talents in Brazil.
