The long-serving goalkeeper for Manchester United says he doesn't see himself playing for anyone other than the club.
The first leg of the last-16 will see him face his old club for the first time since moving to Manchester.
The Spain international has downplayed the occasion but he could face a mixed reception from the fans of his former club.

Instead, De Gea has expressed his love for United and Manchester as a whole, suggesting he would be open to extending his deal beyond 2023.
I like the fact that I was born in Madrid, but at the end of the day, it is just a city.
I feel like anyone else from Manchester. Your home is where you are loved and welcomed.
I've been here for many years and, obviously, anything can happen in life, in the world of football, but I don't see myself away from Manchester United.
I will return to the club that gave me the chance to be who I am today.
This is just another match. Everyone wants to play well and win the match.
I don't know if the fact we're playing them is a good or bad sign. Everyone is going to win.
Since joining United, De Gea has made 473 appearances and is on course to add to his record haul of four Sir Matt Busby Player of the Year awards.
He bounced back from some poor displays in recent years and increased competition from Dean Henderson by showing the mental strength that helped him break through as a teenager.
He said that he was the third-choice goalkeeper at that time.
I used to train a lot and try to prove that I am good enough.
I tried to do my best, but it was fortunate for me that Roberto got injured, and I got the chance to prove that I was good enough.
The team changed when Quique arrived. We won game after game, and there was a moment when Asenjo and I were both available and he chose me.
I played every game. We made it to the final and won it.
We made it to the final of the Copa del Rey. We won the Super Cup after we lost, but at least we made it to the final.
