Chelsea legend Gianfranco Zola believes Diego Costa can make Blues history.

The Spanish striker has been superb for the Blues this season, netting 10 times in Premier League already.

Asked if the 28-year-old was the league's best striker, Zola said: "He is certainly one of them.

"He is very similar to what Drogba was before. He is very tall, very strong, so you can give him high balls and he will handle them.

"But also he is very skilled with the ball at his feet and he is very fast. So you can see he is good and can play in different ways.

"You can always give him the ball and he will make the most out of this.

"He has been exceptional really, he has scored many goals but his contribution has also been good for the team."
