Mateo Kovacic has spoken of his pleasure at seeing the ‘elegant’ Kai Havertz play for Chelsea.

Some doubters remain on the German midfielder following a slow start at Stamford Bridge but Kovacic is content that he will come good.

He told the Blues website: “I like a lot Kai Havertz. He is such a talented player. He is a great signing for Chelsea.

“He will be a huge player for Chelsea and for world football, I’m sure of that. He has huge potential.

“He is such an elegant player. He just needs to learn to play in the Premier League, that’s all.

“It’s a difficult league with a huge tempo, and he will get used to it. Game by game he is getting better so I have no fear for Kai.”
