Arsenal manager, Unai Emery, has said his team will be coming up against one of the top five players in world football, in the Europa League final on Wednesday night.
In order to lift the trophy he won three times with Sevilla, Emery knows he is going to have to stop Chelsea's star man Eden Hazard.
Hazard could well be plying his final game for the Blues ahead of an expected move to Real Madrid and the Spaniard named him along with four other players as the best in the world.
"Hazard is a player of instants, but decisive instants. It is what we have to avoid.
"Chelsea is capable of winning thanks to them, and that ability I have only seen in (Lionel) Messi, Cristiano (Ronaldo), Neymar or (Mohamed) Salah.
"For me, it is the quintet of the best in the world," Emery told El Mundo.
