London: Chelsea manager Jose Mourinho hailed Diego Costa as the complete striker after his side's 6-3 Premier League win over Everton, but is concerned opponents will try to get the Spain international sent off.
Brazil-born Costa scored twice in a thrilling match at Goodison Park on Saturday to take his tally to four goals in three games, and maintained Chelsea's winning start to the season.
Mourinho bought Costa for £32 million ($53.1 million) from Atletico Madrid at the close season. "It was the complete performance of a striker," Mourinho said.
"The perfect performance in every aspect. In the first half he was tackling, he recovers balls, he holds the ball, and his movement was quality. Everything was really good.

Diego had three chances and he scored two goals. He is a good finisher and he gives us a lot. In the end we are killers in attack."
Mourinho was, however, disappointed with the manner in which Everton attempted to provoke Costa during the game which earned him a booking. Mourinho said: "I was not happy with the way some Everton players tried to create problems for Diego.
He is maybe be the best player in the opening EPL matches, but he has two yellow cards. That is disappointing."
