Liverpool vs Porto: Crouch on the bench, Aurelio nowhere to be found

Here's the line-up:
Reina
Arbeloa
Carragher
Hyypiä
Finnan
Babel
Mascherano
Gerrard

Torres

Bench:

Crouch
Kewell
Riise
Sissoko
Lucas
Kuyt

I'm beginning to wander about Aurelio's fitness. He's yet to see action for three weeks now with the international break and two matches since. That's probably part of the reason that Crouch is on the bench since they work best together. Babel starting is a bit baffling as well, his record shows that he's exponentially more the threat as a super-sub, while Crouch is just the opposite. Far from me to question Rafa's tactics, but if it doesn't work out, he's going to have a lot of questions to answer.
