While he is desperate to inspire the Blues to a more positive result than he endured on his last visit, the Spaniard could barely contain his excitement at returning to the stadium so soon.
"Wembley has so much history, English teams have a couple of chances every season to play there and it's massive," he told the official Chelsea website.
"All the players want to play in those games, it's my fifth season in England but this is the first time I'm going there. It's very exciting because we have the chance to reach the final in a London derby, so it will be very nice to be there and to play, so I'm looking forward to it.
"I'd never played against England at Wembley before that game, I'd played against them at Old Trafford, which was nice, but Wembley is so famous. All the Spanish supporters were excited and taking pictures, even the players were taking photos in training the night before.
"If you like football, you want to play at Wembley, I had the chance with Spain, but obviously they're not very good memories from that day as we lost, so hopefully on Sunday it will be better."
