The Spanish international underwent a double hernia operation earlier this summer, causing him to miss the Reds' pre-season tour of the Far East.
However, the 28-year-old is confident of being fit for Liverpool's opening Premier League fixture against Sunderland in two weeks' times.
"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."
Reina joined Liverpool in 2005 after a three-year spell with Villarreal.
