Chelsea striker Alvaro Morata believes Mateo Kovacic is one of the best midfielders in the world and says his new teammate creativity will help him score more goals.
The couple were teammates at Real Madrid before Morata signed for the Blues last summer in a £ 58 million deal, and they were reunited after Kovacic arrived in West London with a loan of a week.
Morata is convinced that Croatian international can be an important player for Chelsea this season and bring some creativity to the team.
"He's a midfielder who's good at the ball, very technical," Morata told the club's official website. "He can break the lines with his quality, he can score goals and he has a lot of power in his legs.
"With him we will win a lot of possession and he has the ability to bring the ball into the final third and provide the passages for the attackers.
"He's a very good player, which is very important to us because we need the best players."
The Spanish striker has faced a difficult period at Stamford Bridge and, despite scoring 12 goals last season, has struggled to claim the solo role.

But the twenty-five is willing to take advantage of his life experience at Chelsea to help Kovacic adapt to life in the Premier League.
"Yes, he gave me a lot of help in Madrid," he says. "We like to play together and I'm very happy to have him here, I think he's one of the best midfielders in the world.
"I always try to help new purchases, I remember that when I arrived here my classmates helped me, and now it's time for me to do the same".
