The Reds fell to a 3-0 defeat at the hands of West Bromwich Albion in Brendan Rodgers's first league game in charge and now face a tough run of fixtures, including matches against both Manchester clubs and Arsenal.
However, Reina is confident that Liverpool can get something out of those games, and believes that the West Brom result was an anomaly rather than a sign of things to come.
"We are getting the ideas from the manager - and we still are - and this is just the beginning. We have to lift ourselves up now and stick together more than ever," said the Spanish goalkeeper.
"It's not normal [to lose]. But I don't think we will see many games for Liverpool like we did on Saturday. There is nothing to worry about. This is just early days. It was a bad game, and it is as simple as that."
Liverpool's next match comes against Hearts in the Europa League on Thursday.
