Successive goalless draws may not have done much for the seventh-placed Reds' hopes of reeling in the teams above them but the clean sheets are certainly welcomed by the Spain international.
He is now third in this Premier League's list of shut-outs behind Manchester City and England's Joe Hart and Chelsea's Petr Cech, whom he faces at Anfield on Sunday.
"I'm happy because we've already kept more clean sheets than last season but there's still plenty of room to improve it," said Reina, who has twice been hampered by injury this season.
"As I said a few months back, there have been a few ups and downs.
"The start of the season was a bit rough to me: since November/December I have probably turned the corner and picked the form up again.
"Hopefully it will stay for long. As I always do, I do my best and work hard on a daily basis.
"I looked after myself a little bit better in the last few months and tried to be as fit as possible.
"It's not about keeping clean sheets, it's about finding the right balance between attack and defence.
"Because of our position in the league, we haven't found it quite yet."
