Spanish international warned to put disappointing World Cup form behind him.
Chelsea new boy Diego Costa has been ordered to make an immediate impact at Stamford Bridge this season to avoid being labelled as another big money flop, the Daily Star reports.
The Blues have reached an agreement to sign the 25-year-old from Atletico Madrid this summer for a fee believed to be in the region of £32 million.
The Spaniard will look to avoid the fate of £50m man Fernando Torres, 30, who has ﬂopped in west London.
And former Blues frontman Andriy Shevchenko – who is another expensive transfer flop himself, has warned Costa that there will be no margin for error in his early days with the club.
“The best thing for Costa is to score and score early,” the Ukrainian said.
“That will be important to him.
“The expectations from the fans and the club are very big so he needs to score and get going.”
Costa set La Liga alight last term by chipping in with 36 goals as Atletico Madrid stunned the Spanish football landscape by trumping Barcelona and Real Madrid to the title. However, he couldn’t replicate that scintillating form in Brazil with the defending world champions.
And Shevchenko added: “I’m sure he will do well. I think he is a good striker and I like him.”
