Valencia captain Dani Parejo knows he faces a massive test against Chelsea midfielder N'Golo Kante tonight.
A victory for either side will earn them a place in the last 16 of the Champions League, while defeat would leave them staring down the barrel of elimination to the Europa League.
"Of course we did a great job and played a great game to win there… you have to be perfect, especially in this tournament," Parejo said.
"(Kante) is a great footballer. He proved it during his season in Leicester. He's a great player, a very important player.
"But they have (many) amazing players. Not only Kante – there is Jorginho, (Mateo) Kovacic, Willian and we have amazing players."
He added: "We are ready to compete against anybody… this has to be a final for us."
