The Blues host the Toffees at Stamford Bridge tomorrow and Mata, who is yet to meet David Moyes' men, feels that the Merseysiders will prove difficult to beat.
"The strikers are tall, they have good players and we have to be prepared with the crosses, which will make things difficult for us."
"Drenthe is a good player, I know him. He is fast, has a good left foot, can score goals and supply crosses. He is a very good player," he added.
"I think he is faster than me! There is that and my play is more inside, he is a winger, winger, winger."
