The 25-year-old has been on strike at St James’ Park all summer as he pushed for a move to the Premier League champions.
Liverpool have now confirmed the record breaking £130 million signing of Isak from Newcastle United on deadline day.
Isak has put pen-to-paper on a ‘long-term’ contract at Anfield and will wear the club’s iconic number nine shirt.
Soon after finalising his move at the AXA Training Centre, the 25-year-old forward told Liverpoolfc.com: “I feel amazing.
“It’s been a long journey to get here. But I’m super-happy to be a part of this team, this club and everything it stands for. It’s something I’m proud of and I’m really looking forward to it.
“I’m just happy it’s done and that I can get back to work. I’m looking forward to seeing my teammates and the fans, and getting back out there.”
Isak added: “I think I have a lot to give, I think I have a lot to improve. I’m a striker but I always want to give as much as possible to the team, mainly goals but much more than that as well.
“I want to win everything. Yeah, (as simple as that).”
This is the second time Liverpool have broken the British transfer record this summer alone having previously paid £116 million to Bayer Leverkusen for Florian Wirtz.
