Donald Trump has risked the fury of NFL fans by teasing a controversial executive order as he attended the FIFA Club World Cup final in New York.

Trump watched from the stands with First Lady Melania and FIFA president Gianni Infantino, as the expanded competition drew to a close.

Chelsea earned a shock 3-0 victory over reigning European champions PSG, with Trump then handed the honour of presenting the trophy.

The US President left both fans and players confused as he remained on stage with Chelsea players during the trophy lift, despite Infantino attempting to encourage him to leave.

Trump risked further controversy in an interview with DAZN about the tournament and the sport as a whole.

Speaking to DAZN reporter Emily Austin, Trump referenced how sport remains known as 'soccer' in the United States compared to football across much of the world.

'It is a big thing [the tournament] and Gianni is a friend of mine, he has done such a great job with the league, with soccer – they would call it football – but I guess we call it soccer,' Trump said.

'I am not sure that change can be made very easily, but it is great to watch.'

Austin then pitched a suggestion to Trump, which could see him oversee the changing of the sport's name in the United States.

‘What if we made an executive order that we can only say football from now on?’ Austin pitched.

Trump quipped in response ‘I think we could do that, I think I could do that.’

If Trump were to follow through on the suggestion, it would likely cause a backlash among NFL fans.

American football has long been referred to simply as 'football' in the United States, with the sport remaining the most popular in the nation.

It is not uncommon though for nations to attempt to transition from soccer to football.

Australia and New Zealand both renamed their national federations to remove mentions of soccer in favour of football, as they attempted to fall in line with the common usage worldwide.

Toward the end of the interview, Trump was asked what his message to viewers around the world would be before the World Cup arrives next year.

'It's about unity, it's about everybody getting together and a lot of love between countries... I guess this is probably the most international sport, so it can really bring the world together,' Trump said.

On the pitch Chelsea clinched the Club World Cup title by beating Paris Saint-Germain 3-0 in front of a sold out crowd in New Jersey.

Cole Palmer bagged a first half brace before setting up new signing Joao Pedro for their third.

Trump took centre stage post-match as he remained as part of the Blues trophy celebrations.

Palmer looked especially confused by Trump's actions and appeared to utter the words: 'What's he doing?'

Trump had earlier presented Palmer with the golden ball award with the 23-year-old midfielder looking as equally baffled during that presentation.

After presenting medals, Trump was spotted front and centre as the Blues hoisted the trophy.

Following his presentation of the trophy to Chelsea, he was asked to leave the stage by Infantino but bizarrely chose to stay put.
