Reina had a double hernia operation this Summer and has missed the start of pre-season training as he recovers. However, the goalkeeper is now fit again, and is line to make his first appearance of pre-season in Monday's friendly with Valerenga.
"The target is to play in Valerenga, and then after Valencia there is one more week and that should be good enough to get that fitness," Reina told the club's official website.
"Just because of precaution, we didn't want to rush it - there was no point in doing that. I'm totally recovered now, training with the team as normal and looking forward. I can't wait to play again.
"It wasn't that nice because my holidays were in the same time as my operation. But after three years without having a proper holiday, I did rest a little bit more this season."
