Adrian admits speaking with AC Milan goalkeeper Pepe Reina before signing for Liverpool.
Reina was happy to recommend his former club to the former West Ham keeper.
Adrian said, “I have spoken to quite a few. Most of all, Pepe Reina, with whom I am very confident and he assured me that I would enjoy very much [at Liverpool].
"He told me I was going to a big club and I will have a great time.
"I've only been here a week, but I'm already aware with the reception I got at Anfield and with the victory at the Super Cup, that it's a club of enormous magnitude."
