BURNLEY, United Kingdom (AFP) — Diego Costa began to pay back his hefty transfer fee with a debut goal for Chelsea as they recovered from the shock of going behind to seal an emphatic 3-1 win over Burnley yesterday.

Spain striker Costa, bought from La Liga champions Atletico Madrid for £32 million (US$53 million), cancelled out Scott Arfield’s opener for Burnley before Andre Schurrle and Branislav Ivanovic scored further goals before half-time to ease Jose Mourinho’s side to an impressive victory in their Premier League opener at Turf Moor.

Having failed to bring a trophy to Stamford Bridge last season for the first time in his two spells in charge, Blues boss Mourinho — and possibly club owner Roman Abramovich — will not tolerate such relative failure again.

The arrival of Costa therefore came as a serious show of intent, and Chelsea’s determination to dethrone reigning champions Manchester City was further underlined as they went top of the table after a dominant performance inspired by a masterful debut from Spain midfielder Cesc Fabregas.

The newly promoted Clarets’ last visit to the top-flight in 2009-10 had brought a memorable opening home win over Manchester United, and the fixture list presented them with an opportunity to make a similarly spectacular entrance.

While Chelsea’s squad assembled over the years at a cost of around £190 million, Burnley’s cost nearer £6 million, with only one member of their starting line recruited in pre-season for a fee in the shape of former Middlesbrough striker Lukas Jutkiewicz.

But despite that gulf, Burnley briefly looked like upsetting the odds when they took the lead in the 13th minute.

Five years ago it had been Robbie Blake who had been Burnley’s hero with a thumping volley and Arfield’s strike didn’t suffer much by comparison.

The opening began with a corner which was only cleared as far as Burnley defender Michael Duff and he headed the ball back to Matty Taylor.

Taylor’s cross eluded the bodies waiting in the penalty area, but not midfielder Arfield, who controlled the ball 20 yards out and sent a dipping volley beyond Belgian goalkeeper Thibaut Courtois, selected ahead of Petr Cech, and into the roof of the net.

Burnley couldn’t have dreamt of a better start, but the goal served only to wake up Chelsea and after Costa’s equaliser four minutes later there was going to be only one winner.

With none of Chelsea’s strikers reaching double figures in the Premier League last season, the Spain international was recruited by Mourinho to give his side more of a cutting edge and he delivered straight away, driving home a loose ball after Burnley captain Jason Shackell had deflected a cross from Ivanovic against a post.

And four minutes later Chelsea were in front thanks to a flash of inspiration from former Barcelona star Fabregas.

His first-time pass which split Burnley’s defence was sublime, and Schurrle took full advantage of the service as he ran through to side-foot into the net.
