Diego Costa has had a good season so far at Chelsea, but is in the worst run of his Chelsea career, having not scored a goal in his last four league games.

However, Chelsea legendary striker Didier Drogba believes Costa will come good at the end of the day.

“Before he would be so frustrated not to score,” Ivorian legend Drogba said of Costa. “Now he’s growing – like every player.

“He’s improving, he knows the league better, he knows the referees and the players.

“He’s focusing more on his game, like I did after a few years in the league.”

Costa has already scored 17 goals in the Premier League this season.
