This term a hamstring injury kept him out for a month and stand-in Brad Jones' displays - plus a dip in Reina's early-season form - have left him scrapping for his place.
Reina, 30, finally returns today and Kop boss Rodgers said: "I have absolutely no qualms about Pepe.
"He is intent on making himself a better keeper and when we have that, we have one of the best in Europe.
"It's all about confidence and losing confidence happens to every keeper - look at Joe Hart against Sweden.
"Pepe is our No 1 keeper and I know that he's committed and determined to continue at the top for the next nine or 10 years.
"But it's important for any player to know they have a challenge."
