Benfica star Pablo Aimar regards Chelsea defender David Luiz as a real danger in this week's Europa League final.

Aimar, 33, won the UEFA Cup with Valencia under Rafa Benitez nine years ago.

Now interim Chelsea boss Benitez and his Blues, including Luiz, await in tomorrow's Europa League final.

Aimar said: "David has all the quality to be the team leader. We need to nullify him to win."
