The football club completed a deal with McAlister for £35M to sign him from Brighton to a five-year contract. It is estimated that the fee could rise to £55M for the Argentinian who helped his former club finish in sixth place in the Premier League this season, helping them qualify in Europe for the first time.
He was also instrumental in Argentina’s history World Cup win last year.
“It’s a dream come true and I can’t wait,” said Mac Allister.
“I wanted to be in [from] the first day of pre-season, so it’s good that everything is done. I’m looking forward to meeting my teammates.”
“It was a fantastic year for me - World Cup, what we achieved with Brighton - but now it’s time to think about Liverpool and try to be a better player and a better human being every day.”
Liverpool’s manager Jurgen Klopp is reinforcing their midfield force with McAlister since James Milner, Naby Keita, and Alex Oxlade-Chamberlain are leaving soon.
They were planning to get Jude Bellingham but were priced out by Real Madrid.
“Since I won the World Cup, I said that I want to win more trophies and I think that this club will help me to do that,” said Mac Allister.
“That’s the aim and when you are in a big club like this one you have to win trophies.”
“I can see how big this club is - the players we have, the staff, everyone. I’m really pleased and looking forward to playing for this club.”
He also took the time to say thanks to Brighton.
“I never thought I was going to live what I have lived in these three and a half years, but this club gave me that opportunity and I’ll be forever grateful,” he said on Instagram.
“I don’t have any doubts that this team is going to achieve many important things, because they have the football skills and human quality to do it.”
“I’ll always watch you and support you. Thanks a lot, Seagulls, you will always have a special place in my heart!”
