The forward sealed a transfer to the Reds earlier this summer while he was in North America as part of Spain's World Cup-winning squad.
Back in March, meanwhile, the 23-year-old scored on his international debut, which he earned partway through an eye-catching campaign in La Liga with Osasuna.
Reflecting on the past eight months, Munoz said: "Stuff's happened really, really quickly this whole year, but as a person I try to take these things in my stride and calmly.
"But it has been an amazing year with everything that's happened and everything's been really positive as well.
"I've been very happy how things went, playing in Spain and then getting the chance to represent the country at the World Cup – that was like a dream come true, being a part of all that.
"And now signing for Liverpool, it means that the year's going to continue and hopefully end in a real positive way as well."
He added: "I can't wait to get under way with playing in the league season.
"But in terms of my aims and objectives, initial ones are to get used to the pace and the speed of the game here in England, to grow as a player and also to just try to improve with every day that goes by in training and then in games."
