LONDON - Chelsea's new striker Diego Costa scored two goals in seven minutes with his first coming 57 seconds into his home debut in a 2-0 friendly win over Real Sociedad.
Blues boss Jose Mourinho spent much of last term complaining about his lack of quality attacking options and Romelu Lukaku, Samuel Eto'o and Demba Ba have all been sent packing to make room for Costa and returning Chelsea legend Didier Drogba.
On the evidence of Costa's maiden outing in west London, the STG32 million ($F100million) Mourinho splashed out to sign the 25-year-old from Atletico Madrid should prove an astute investment.
The Spaniard was on the scoresheet with a cool finish less than a minute and he added a second goal in the seventh minute, while proving a constant threat to the Sociedad defence before being replaced to a standing ovation on the hour yesterday. Although Costa was the headline act, Mourinho would also have been encouraged by a solid home debut from Spain midfielder Cesc Fabregas.
