Chelsea boss Jose Mourinho believes newly signed striker Diego Costa will prove a bargain buy, following his impressive display in the pre-season clash, and his clinical double in the 2-0 friendly win over Real Sociedad.
The Blues splashed a staggering £32 million to lure the 25-year-old talisman Atletico Madrid and the Portuguese manager is convinced that the scrupulous attacker will justify his hefty price-tag by the end of the season.
Mourinho said: "Diego is a team player, he works a lot, he is not just about goals. He is about defensive work, his mentality, his ambition.
"This is why we didn't buy a striker in the last transfer window - we were waiting for him.
"He looks very adapted to his team-mates and the style of play.
"I won't say he is adapted to the Premier League yet because it is a very difficult job to be a striker in this country, but hopefully he does well.
"You can consider that it is a bargain because the market is crazy.
"The values for strikers are very high, so for a young striker like him, a champion in Spain and a Champions League finalist, you can say the price Chelsea paid is very much in our favour."
Chelsea will travel to Burnley for their Premier League opener on Monday.
