Llorente played like Morata did yesterday, I would be overjoyed. He assisted one goal, his deflected cross created the other goal. He made several nice passes that set up other chances, he held the ball up well when asked, plus won the ball back in the attacking half more than once. His pace also allowed us to counter effectively.
Llorente can't pass, doesn't create chances for others, his hold up play has been terrible this year, and he never wins the ball back. He fouls defenders quite frequently with his clumsy attempts to get the ball back after he gives it away.
Morata wasn't brilliant, but he was good, better than Llorente has been in 95% of his matches this year. As soon as Morata gets his finishing down, he will be a very good striker.
