Guus Hiddink: I’m very proud of this Chelsea star

Hiddink is pleased with Costa’s performances this season, insisting that his actions do not cross the line.

"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," Hiddink said.
"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 also this problem not scoring, as did the team. Let's see and hope he can make it to the European level as well."
Costa has netted 14 times for the Blues this term having struggled under Jose Mourinho at the start of the campaign.
His performances have picked up since Hiddink’s arrival but the 27-year-old has been linked with a move away from west London in the summer.
