Liverpool signed Brazil's Alisson from AS Roma on Thursday making him the most expensive goalkeeper ever in the process.
"I'm really happy, it's a dream come true to wear such a prestigious shirt for a club of this size that is used to always winning", Alisson told liverpoolfc.com.
"I'm anxious because I'm not training (with everyone) and then I go to the Premier League without lots of players, but it is what it is and we have to try and make the best out of it with the players we have here".
Alisson began his career at Internacional in his homeland of Brazil.
That is why the most expensive goalkeepers have remained so far behind the most expensive outfield players.
Alisson broke the world record transfer fee for a goalkeeper after completing his move to the Premier League side for £65m.
"But no, at the moment we have three outstanding goalkeepers and two very young and very talented goalkeepers but we need that, so I'm happy about that".
Israeli soldier and four Palestinians killed in Gaza Strip clashes
More than 135 mostly unarmed Palestinians have been killed by Israeli fire since the border protests began on March 30. Israel and Hamas later agreed to restore calm along the Gaza Strip following the flare-up which lasted several hours.
We didn't sign him because he is good looking and a nice fella and his English is good and all that stuff - we signed him obviously because he is a world-class goalkeeper. We were not too bad previous year but we had to improve and we tried that on the transfer market.
Liverpool manager Juergen Klopp says clubs will be "collecting the bones" of overworked players as the global calendar places more demands on teams already struggling to cope with a hectic domestic schedule.
But while the mere mention of Loris Karius' display at Kiev's Olimpiyskiy Stadium is like to send Liverpool supporters into despair, they can rest assured that Alisson is a fine shot-stopper who played an outstanding role in Roma's impressive campaign last season.
"The full package is just too good".
He had only 83 first-team starts to his name when he moved to Roma in 2016, acting as Wojciech Szczesny's deputy for a season without starting a game in Serie A. The former Arsenal man's move to Juventus presented Alisson with his chance, and he made 37 league starts as Roma finished third and reached the Champions League semi-finals.
"It shows the value of goalkeepers, of course, in this moment".
"When you make an important decision like this it's not just a decision to change clubs, it practically changes your entire life, my family's life, my wife, my daughter".
The signing of Virgil van Dijk in January was significant, with Klopp's side recording more shut-outs from the Dutch centre-back's debut in Gameweek 24 onwards than any other Premier League side.
