David Beckham admitted that he 'didn't realise how big a challenge it was going to be' to establish Inter Miami as the latest club in Major League Soccer.
The legendary co-owner and president, speaking at the 2020 MLS launch on Wednesday, opened up on the difficulties to get to this point but remained adamant that he never once considered giving up.
'It has been a long journey. But I always knew it would be worth it,' he said.

'I had a long and successful career in the game but I have always loved a challenge. I didn't realise how big a challenge it was going to be. It took longer than I thought.
'There were moments when I thought this might not happen, but there wasn't a moment when I said I would walk away.'
Inter Miami are one of two MLS expansion teams being added for the 2020 season with Nashiville SC the other, taking the total number in the league to 26.

The process in getting everything sorted for the first game has dominated Beckham's time and he admits he has learned about himself in the process.
'I'm more persistent than I thought I was,' he added. 'And I'm more stubborn than my wife thinks I am.'
Beckham's team will make history with their first ever MLS game on Sunday when they take on Los Angeles FC.
The ex-Los Angeles Galaxy midfielder was expected to make a number of marquee signings to kickstart the club's first season.
But Beckham insisted earlier this week that he is happy with the squad at his disposal, despite Inter Miami failing to bring in a third designated player.
They have already acquired Matias Pellegrini and Rodolfo Pizarro ahead of their opener.

Miami confirmed last month that they had held talks over a shock move for Edinson Cavani, only for him to remain at PSG until the end of the season, while Luka Modric has also been targeted.
After posing for pictures with players and staff during a media day at Fort Lauderdale on Tuesday, he said, via Miami Herald: 'I am not disappointed in any way possible because I know this has taken seven years.
'A lot of you have seen those seven years unfold, there's been some frustrating times, but someone turned around to me the other day and said: "What would be success for this team and this franchise?" For me, on March 14, when we step onto our stadium in front of our fans, for me, that's success because I know what it's taken to get here.
