Chelsea boss Guus Hiddink defends Diego Costa and Eden Hazard

Chelsea interim boss Guus Hiddink has defended Diego Costa and Eden Hazard ahead of Wednesday night's Champions League clash with Paris Saint-Germain at Stamford Bridge.

PSG's social media team upped the ante on the eve of the last-16, second-leg tie with a video montage of masked super heroes titled 'Spot the fraud', which also included Costa, who has been playing with a protective mask due to a broken nose.

PSG manager Laurent Blanc warned his PSG players to stay cool when facing Costa, who has scored 10 goals in 14 games under Hiddink, but has just one Champions League goal in two seasons and 14 games with the Blues.

 Costa, available after missing Saturday's 1-1 draw with Stoke as a precaution over a minor tendon problem, has a reputation for riling opponents.

He has never been sent off for Chelsea, although he has served two retrospective three-match domestic bans in his two seasons in London.

 "I'm very proud of him the way he's playing and, going not over the edge, but he likes to fight in the real way of the game," said Hiddink, whose side are looking to get back into the tie after losing the first leg in Paris 2-1.

"That's what we like. I protect him and support him when he's doing what he has done in my period at Chelsea.

"He scored recently in not the worst league in the world. In the Premier League he frequently is scoring now, since December, January.

 "Before he had this problem of not scoring, as did the team. Let's see and hope he can make it to the European level as well."

Hiddink also issued a robust defence of Eden Hazard ahead of the game.

The Belgium playmaker, Chelsea's leading performer in last season's Premier League and Capital One Cup double, has struggled for form this campaign.
