Diego Costa has been urged to hit the ground running at Chelsea.
The Spaniard will look to avoid the fate of £50m man Fernando Torres, 30, who has ﬂopped in west London after completing his £32 million move from Spanish giants Atletico Madrid.
And Andriy Shevchenko warned Costa there will be no settling-in period.
As quote on the Daily Star website, the Ukrainian said: “The best thing for Costa is to score and score early.
“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.”
