Cesar Azpilicueta is convinced that Diego Costa will not become Chelsea’s latest big name flop forward.

The Spain international is set to make his competitive debut for the Blues this evening against newly promoted Burnley, and has been backed to score the goals Jose Mourinho cried out for from his front men last season after costing the club £32m.

During the Roman Abramovich era Didier Drogba has, arguably, been the Londoners’ only massively successful striker, with big fees for star players having not been rewarded with goals on a number of occasions.

Perhaps the finest example of this is Fernando Torres, who has proven to be a woeful acquisition at £50m from Liverpool in 2011, while Andriy Shevchenko and Hernan Crespo have also disappointed.

But with Costa having scored more than 30 times for Atletico Madrid last term and added another four to his impressive tally in pre-season with Chelsea, Azpilicueta is sure that he will do the business for his new side:

“It’s easier when you have a big transfer like this if you start scoring goals straight away and get confidence — and that’s what he’s done.” He told the London Evening Standard.

“Will he make an impact in the League? We hope so. He is adapting to the team and the club, and hopefully he will score a lot of goals.”
