Mark Jones: If Kansas City win SBLIV, has Andy Reid cemented his position, as one of the modern era's great head coaches?

Joe Evans: Do you think that the warm Miami climate gives the 49ers an advantage as they’ve been used to playing in warm weather in Santa Clara whilst the weather in Kansas City has been freezing recently?

David Wright: Giving it a go, made it as far as half time the last few years. Hoping #SBLIV is entertaining enough to keep me awake all night.

You can do it, David!

This is electric, we can't wait to get it started so imagine what the players are going to be feeling.

To mark 100 years of the NFL four 100-year-olds are going to take part in the coin toss - all World War II veterans adding another chapter to some amazing lives.

Charles McGee flew 136 combat missions over Italy and Romania and had a lovely understated response to tonight's responsibilities.

"It was quite a thrill to be asked,’’ he said. "I couldn’t say no."

Worth noting that teams to win the coin toss have lost five consecutive Super Bowls.

Sprint legend Usain Bolt's also in town...

I expect basketball legend Shaquille O'Neal had a similar exchange tonight with Marcus Rashford.

The injured Manchester United and England striker will be watching the game alongside some famous faces - including Shaq and Hollywood actor Kevin Hart.

There's going to be some parties in Miami tonight. And this guy is the man to see.

Celebrity host Purple admits he had to Google who Sergio Aguero was though.

Apparently the first two Super Bowls weren't shown live on TV and the footage was taped over by soap operas.

They were thought to be lost forever until one fan had both on tape. Don't think there's much chance of tonight's action going missing across the globe...

The New England Patriots have appeared in the last three Super Bowls, winning two of those games. Tonight, head coach Bill Belichick will be spectating the event from the stands rather than the sidelines for the first time in four years.

We're now live on BBC Two, before switching to BBC One at 23:25 GMT.

But you can watch all the action by clicking on the play icon above.

The 49ers have the scariest defence in football, just ask Jason Bell. All of their defensive line have been getting after the quarterback, with Nick Bosa leading the way. This weekend the defensive end was named Defensive Rookie of the Year after registering nine sacks in the regular season and another three in the play-offs.

George Kittle is a wrecking ball of a tight end and with Travis Kelce playing for the Chiefs, we could be watching the most entertaining tight end duo in Super Bowl history tonight. Kelce led the 49ers with 1,053 receiving yards in the regular season and helped them to a crucial win over the New Orleans Saints in week 14. Trailing 46-45 with 39 seconds left, Jimmy Garoppolo picked him out and Kittle kept running despite an opponent holding onto his facemask. It even took another two men to bring Kittle down after a whooping 39-yard run, which set up the game-winning field goal.

Raheem Mostert has a point to prove. He's already been cut by six teams and apparently carries a note with all the cut dates on to give him motivation. And it's clearly worked in the post-season as the running back racked up four touchdowns and 220 rushing yards in the NFC Championship game against the Green Bay Packers.

But it's not all about the quarterbacks. And there's no way you can make it all the way to the big show by being a one-man team. So here's some of the other key men for each time, beginning with the Chiefs.

Wide receiver Tyreek Hill is nicknamed 'Cheetah' for a reason. The 25-year-old once clocked 9.89 seconds over 100m (admittedly a little wind-assisted) and hopes to earn a place at the Tokyo 2020 Olympics. When any of his team-mates streak clear for a touchdown he usually catches up to escort them into the endzone. Why? Well, just because he can.

Tight end Travis Kelce is Patrick Mahomes' go-to man. With the Chiefs trialing 24-0 to the Houston Texans in the play-offs, who does he turn to? Kelce. He hit the 30-year-old with three touchdowns in the second quarter as the Chiefs staged a stunning fightback to win 51-31.

Tyrann Mathieu earned the nickname 'Honey Badger' for his ability to hunt down the ball and the opposition and shows the Chiefs are not just about offence. The 27-year-old safety had the most interceptions (four) and the third-highest number of tackles (75) for the Chiefs in the regular season.

Expect a few tributes to basketball legend Kobe Bryant tonight.

The LA Lakers superstar died in a helicopter crash alongside his daughter Gianna and seven other people a week ago today.

49ers reciever Emmanuel Sanders will be wearing these boots, featuring both of Bryant's numbers.

Most NFL fans would agree, this is arguably the best match-up the league could have thrown up this season.

Patrick Mahomes was the league's MVP last season and could become the first quarterback to win the MVP award and Super Bowl before turning 25.

Jimmy Garoppolo was groomed to be Tom Brady's successor at the New England Patriots but was traded to the 49ers during the 2017 season and was injured in 2018 but has led the 49ers to the Super Bowl in his first full season as a starter.

• The 49ers would record their sixth Super Bowl victory, tied with the New England Patriots and Pittsburgh Steelers for the most Super Bowl titles by one franchise. San Francisco also captured Super Bowls 16, 19, 23, 24 and 29.
• The team would become just the second club in NFL history to win a Super Bowl after finishing the previous season with four-or-fewer wins, joining the 1999 St. Louis Rams.
• San Francisco would win the Super Bowl for the first time in 25 years. At the same stadium, on 29 January, 1995, the 49ers concluded the NFL’s 75th season with a 49-26 victory over the San Diego Chargers in Miami.

• Nearly 50 years to the date of their last Super Bowl appearance (11 January 1970, Super Bowl 4), the Chiefs would have their first world championship in five decades.
• Coach Andy Reid would win his first Super Bowl. Reid would have 222 career wins, including post-season. Only five coaches in the history of the league have more victories, including the post-season.
• Quarterback Patrick Mahomes would become the second-youngest quarterback ever to win a Super Bowl (Ben Roethlisberger, Super Bowl 40).
