Real Betis coach Quique Setien is under no illusions of the strength of Atletico Madrid's attack ahead of their meeting on Sunday.

New arrival Alvaro Morata could accompany Antoine Griezmann in attack and, despite his poor form in the last year, the Betis coach still believes he is among the elite and will show it again.

"I'm not going to say who [of the two] is better, but we already know that Morata is a great footballer and Chelsea paid Real Madrid 80 million euros for him," Setien said at his press conference.

"He's a young kid, he's eager and full of hope even though he hasn't been at his best lately.

"He's a great footballer, just like the teammate he will play with.

"Both Morata and Griezmann are two of the best strikers in the world."
