There are Champions League winners wherever you look in these line-ups. Two teams overloaded with European football's creme de la creme.

Meanwhile, former Real Madrid defender Achraf Hakimi is lining up for PSG, while ex-PSG forward Kylian Mbappe is lining up for Real Madrid.

This really is a Club World Cup blockbuster.

Kylian Mbappe hit a cameraman with a wayward shot during his shooting practice before the match.

Such was the power of the effort, it completely wiped out the photographer but the Frenchman went over to make sure that the man was feeling okay. An unfortunate occupational hazard.

How many miles have Real Madrid clocked up in 2024-25?

Their schedule has been mind-blowing.

As well as 38 La Liga games, 14 Champions League matches and six Copa del Rey ties, Real have played two Supercopa de Espana games in Saudi Arabia, competed in the Uefa Super Cup in Poland, played in the Fifa Intercontinental Cup final in Qatar, while this is their sixth game at the Club World Cup.

In the past month alone, Real have played games in Florida, North Carolina, Pennsylvania and New Jersey.

Kick-off is approaching.

Fireworks inside the ground as PSG's players start to emerge.

One-by-one, of course.

This is the first time Kylian Mbappe has faced Paris St-Germain since leaving to join Real Madrid last summer.

The 2018 World Cup winner with France - PSG's greatest goalscorer with 256 goals - left to win the Champions League but Real got knocked out by Arsenal in the quarter-finals who then got knocked out by PSG in the semis as Mbappe's former club went on to win it for the first time.

Mbappe's debut season in Spain also included finishing runner-up to Barcelona in both La Liga and the Copa del Rey.

He'll be desperate to get his hands on the Club World Cup.

Superstar forward Kylian Mbappe remains in a legal dispute with his former club Paris St-Germain over bonuses and salary worth €55m.

Also, before kick-off, multiple French journalists tried to get manager Luis Enrique to talk about his former player but he wouldn't be drawn into any kind of comments about Mbappe, positive or otherwise.

It serves to highlight a fraught backdrop to this match as PSG's all-time top scorer Mbappe faces his former employers here in New Jersey for the first time as a Madrid player.

There are fans wearing Kylian Mbappe shirts all around the MetLife Stadium. There's a fair few with 'Bellingham' on the back of their tops as well. It's feels like a home game for Real Madrid.

A reminder that we should be kicking-off now but it has been put back 10 minutes due to both teams arriving late at the ground due to traffic.

Most people believe this year's Ballon d'Or - with the nominations due in August - is a straight race between Ousmane Dembele and Barcelona's Lamine Yamal. It has been eight years in the making for the former.

His talent has never been in question.

France striker Dembele was once the second-most expensive player in the world when he signed for Barcelona from Borussia Dortmund in a deal worth £135.5m in 2017 and, four years later, was described by Barca president Joan Laporta as "better than Mbappe".

A week later, the newly-appointed Barcelona manager Xavi Hernandez said he was a player who "when used properly, could be the best player in the world".

Four years on and with his six-year spell of inconsistency and unfulfilled potential at Barcelona behind him, Dembele is certainly being used properly.

He has scored 34 goals and made 15 assists in 51 matches in all competitions in the season of his life so far, with those close to him adamant his form warrants the ultimate accolade on 22 September.

Arsene Wenger is looking well. The former Arsenal boss is inside the ground signing autographs for fans.

By the way, the weather is good in New Jersey. Blue skies above the MetLife Stadium.

Kick-off might be delayed due to traffic, but I don't think we're going to have any weather delays.

This is taking place at the MetLife Stadium in New Jersey which will stage the World Cup final on 19 July, 2026.

Will England be playing here in 12 months time - or will Thomas Tuchel be toast by then?

Paris St-Germain boss Luis Enrique, on what is a seismic fixture: "Playing against Real Madrid is always a special game. They are the most decorated club in the world.

"We are delighted to be playing in a game like this because it means we have done a good job up to now.

"We are very close to playing another final and that is a true motivation."

DAZN are reporting that kick-off will be delayed by 10 minutes with the game now starting 15:10 local time (20:10 BST).

The reason given is that both teams arrived at the ground 20 minutes later than planned due to traffic.

This is Jude Bellingham's 100th appearance for Real Madrid.

The former Stourbridge Juniors player has one La Liga title and one Champions League triumph since moving to Spain's capital two years ago.

"Everyone knows that 100 games for Real Madrid is a great dream come true and a great achievement," says the England midfielder.

"To be able to represent this club 100 times is incredible, a great achievement for me and my family. I hope there will be another 100 after.”

Bellingham adds: "We're coming to the end of the competition. We've been here for three weeks and it's been a great experience.

"We've had good training sessions preparing for a tough match against the reigning Champions League holders. We know it'll be a difficult game, but we'll do whatever it takes to win."

We want to hear your thoughts on tonight's semi-final - and Sunday's final. Will Paris St-Germain beat Real Madrid and stay on course to finish 2024-25 with five trophies - or will Thibaut Courtois and Antonio Rudiger set up a reunion with their old club Chelsea in the final.

Will Enzo Maresca's side kick-off their Premier League campaign on 17 August as Fifa Club World Cup champions? And what are your thoughts about a Super Bowl-style half-time show in the final?
