Usain Bolt's announcement that he will be going on trial at Borussia Dortmund got our thinking caps on here at Bundesliga towers, leaving us to wonder what a dream XI made up of sport's other biggest names would look like.

Turning to a 4-4-2 formation in order to shoehorn in this galaxy of superstars, this is what we here at came up with...

Goalkeeper: Harumafuji, sumo wrestling

It's a lesser-known football truism that every great team is built on a big Mongolian in goal. Well, big is relative: Harumafuji was always one of the lightest men in sumo wrestling's top flight, the Ulaanbataar native in 2012 becoming the lightest man in the highest division for 20 years.

Still, weighing in at a mere 137kg/302lbs, Harumafuji would be a nightmare for opposing strikers in one-on-one situations. On top of that, according to Wikipedia the 34-year-old has long been "noted for his technical skill," leading to suppositions that he'd be more of a shot-stopper than a sweeper-keeper.

Right-back: Lewis Hamilton, Formula 1

Motoring down the right flank in our fantasy XI is Hamilton. An aggressive, risk-taking driver by nature, the four-time F1 world champion would be more Bayern Munich's Joshua Kimmich than Wolfsburg's Paul Verhaegh in terms of style. Given that his day job involves sitting in a hot car for hours with only one straw from which to drink, stamina would not be a problem for the lifelong Arsenal fan.

Centre-back: The Rock, wrestling

Hamilton's natural attacking tendencies would be no problem in this team, built as it is on a rock at the back. For size alone, Dwayne Johnson (6 ft 5in; 118kg/260lb) would represent a formidable obstacle for opposition attackers to find their way around, but we suspect there's also some hidden positional understanding in there: the eight-time WWF/WWE champion played defensive tackle and linebacker during his college football days in Miami.

Centre-back: Anthony Joshua, boxing

Having already turned out at Wembley and gone (almost) the distance with none other than Dr Steelhammer, Wladimir Klitschko, neither sense of occasion nor stamina would be a barrier to Joshua settling in seamlessly in the heart of defence. Nor would the odd tussle in the penalty area – "letting him know you're there" – be a problem for the 28-year-old, who has won all of his 20 fights by knockout.

Left-back: Rafael Nadal, tennis

According to what his lifelong friend Joan told Marca last April, after Nadal had won his 10th French Open title, "From a very young age Rafa was very good at football, he was a centre-forward. I think he liked football more than tennis back then."

The nephew of former Spain international Miguel, Nadal has long been a football fan, noted for his support of Real Madrid and hometown team Real Mallorca, but in our team we're shifting him to left-back, from where he'd launch one swashbuckling raid after another down the flank.

Right wing: Le'veon Bell, NFL

Enjoying a fine year with the Pittsburgh Steelers, running back Bell would be a right winger to be reckoned with both for his direct, powerful running and his ability to find the gaps.

"If there's a gap open, he's going to find it," Jacksonville Jaguars' defensive end Calais Campbell said ahead of facing Bell this weekend in the NFL Divisional Round play-offs. "You understand that you have to be in the gap or otherwise, he’ll beat you." Sounds perfect for our XI.

Central midfield: Tom Brady, NFL

There's a reason that in football parlance of recent years, a holding midfield creator has become known as the quarterback (think peak Xabi Alonso). That reason is perhaps Tom Brady.

Quite simply, who better to have pinging passes around from the base of an attacking formation than one of the NFL's greatest ever players and a five-time Super Bowl winner? Clutch in the big games, even at 40, Brady would run the show.

Central midfield: Conor McGregor, boxing/MMA

The best midfield pairings tend to be formed of one creator and one destroyer (think of Bayern Munich's 2012/13 treble-winning season with Javi Martinez and Bastian Schweinsteiger). With Brady taking on the creative artistry, who better to be in the destructive role alongside him than Conor McGregor?

With his mixed martial arts and boxing skills, the roguish Irishman would gleefully snap at opponents' heels all day long, providing the perfect platform for the other midfield stars to get to work. Oh, and imagine the behind-the-scenes Instagram footage.

Left wing: Steph Curry, NBA

Three-point play is a regular theme when Curry is around, so just imagine how lethal his shooting from outside the box would be when stationed in a left-wing position – James Rodriguez and Naby Keita, eat your hearts out.

Striker: Usain Bolt, sprinter

Where else is the fastest man on the planet going to play other than centre-forward? Think Bayer Leverkusen's Leon Bailey, but much, much faster. Next, please.

Striker: Dirk Nowitzki, NBA

With all the individual mavericks in the side's attacking line-up, someone has to do the dirty work and tee up Bolt. That's where Nowitzki comes in.

A power forward by name and by nature, the seven-foot German could be just the man to win the aerial duels and flick it on for his Jamaican partner to chase. It would no doubt be one of the less conventional little-and-large pairings of all time, but it would work a treat. Also an underrated shooter in his own right, watch out for Nowitzki's long-rangers every so often.
