London - Serbia striker Aleksandar Mitrovic's pivotal role to Fulham's return to the Premier League earned him a permanent move from rivals Newcastle on Monday and he declared himself "happy to the moon and back".
The 23-year-old - who scored 12 goals in 17 appearances for the Cottagers after joining them on loan in January - cost a reported A look at the profile of Premier League side Manchester City ahead of the 2018-19 season £22 million and signed a five-year contract.
"I'm very glad and happy and proud to finally be here and officially become a Fulham player. I'm happy to the moon and back," he told Fulhamfctv.
"I have love for the fans. They're amazing fans and I have a really good connection with them.
"This is a big club and last year we made history, we did big things, and I want to continue this. We want to keep making big things, and with all the fans behind us I think we can go far."
Fulham vice-chairman Tony Khan said he is delighted to have secured Mitrovic - who scored 17 times for Newcastle in three years - as he had been a target since his successful stint there.
"He was a hero in our run to promotion, and from the moment he arrived at Motspur and began working with us, we've always wanted Mitro on a permanent," said Khan.
"I told him that after the final at Wembley, and I'm thrilled to make it official today."
Mitrovic, who played for Serbia at the World Cup and has 17 goals in 40 international appearances, is the fifth recruit by his fellow Serb and manager Slavisa Jokanovic.
The club spent a reported 35 million on Ivory Coast star Jean Michael Seri and French team-mate Maxime Le Marchand from Ligue 1 side Nice, while also bringing in Germany's 2014 World Cup-winning winger Andre Schuerrle from Borussia Dortmund on loan and buying goalkeeper Fabri from Turkish outfit Besiktas.
Fulham returned to England's top flight by winning promotion last season via a play-off, after four years in the Championship.
