Tottenham are ready to sign the Argentine over the weekend.
The 27-year-old has a €10m buy-out clause in his contract and so Europa League holders Sevilla are powerless to stop his departure.
Emery said before the season kicks-off against Valencia on Saturday: "There is no chance that he will be playing for us this weekend.
"He is one of the pillars of the team but we will just have to find another player to take his place. I'm happy for him. We want him to stay but this is what happens when you win things."
