Erling Braut Haaland is actually the second person in his family to pull on a Manchester City jersey and play for the club. His father, Alfie, had a spell at “the Citizens” in 2000, meaning that Erling was actually born in England.

Haaland junior also spent his youth at Bryne FK, where his agility and speed saw him move up to play alongside older boys. From there, his rise has been meteoric, with the Norwegian striker now one of the best-paid footballers in the world. The Viaplay documentary, Haaland – The Big Decision, joins the number 9 as his stint at Borussia Dortmund comes to an end. He must make a choice – which of the world’s biggest clubs will he join next? “You have the whole world at your feet … what could go wrong,” reporter Jan Åge Fjørtoft asks. “Nothing … it’s going to be damn fun,” Haaland replies with a mischievous grin.

The documentary features a range of talking heads, from his former footballer father to Ferran Soriano (CEO of Manchester City). It’s through chats with his siblings and his Norway teammates that we get a real sense of the man. Indeed, the opening clips show that – for all the designer shoes and watches on display – Haaland is still a messy twenty-something piling up dirty laundry on his couch. “You were a little bastard … very childish,” his compatriot colleagues observe of his early career, where egregious goal celebrations were the norm. With a €60 million price tag on his head, it’s clear that Haaland has done a lot of growing up.

Revelling in his outrageous collection of goals, director Tommy Barstein shows montage after montage of goals that seemingly defy the laws of physics. “This boy will disappear abroad before we get a sigh,” one Norwegian football commentator accurately predicts during his early career. Haaland scored a hattrick in his Champions League debut. He did the same in his first game for Borussia Dortmund. Constantly scanning for opportunities to assist or score himself, the young prodigy breaks record after record. Indeed, his time in Germany is met with a sea of yellow and black; adoring fans who respect their beloved striker.

And perhaps the reason he can do so is “Team Haaland”, a small group of people who do all of the thinking for the player so that he can focus on football. Comprising of family, agents and advisors, the team take all of his life decisions, from the big (which sponsorship he will obtain and which clubs he will play for) to the small (which bank he should choose and which car insurance is best). Alfie Haaland makes choosing his son’s next club sound like a science. There’s a points system based on things like how well Erling will adapt to the team’s style of play to the general standard of the league. It’s a system that is constantly in motion, with the likes of Paris Saint Germain, Real Madrid, Liverpool and Barcelona in the mix.

But it’s Haaland’s potential connection to Bayern Munich that causes the most drama. With their current striker, Polish superstar Robert Lewandowski approaching the end of his career (at age 34), there were rumours swirling in the press that Haaland would be next to lace up the number 9 boots at the German giants. This caused such tension and bad feeling that Lewandowski promptly exited the club.

Negative press is something that is only explored towards the end of the documentary. “I do one thing and there are fifteen articles about it,” Haaland sighs. His outfits are made fun of; his goal celebrations seen as provocative. We get some small insights into his diet and lifestyle – local, organic meat, following his circadian rhythm and filtrating his water – but not enough to really burrow under his skin. “Why should they [the press] know who I am? I feel like putting on a front.” Perhaps it is only Team Haaland, then, who really get to know the (undoubtedly under pressure) star, despite the constant presence of cameras in his life.

The documentary ends with his arrival at Manchester City, the club that emerged at the top of Alfie’s points system. Donning the sky blue kit with a braid in his hair, the 6 foot 4 striker looks like something out of a Viking myth. “I don’t really pay attention to records,” he says grinning, “But what is Shearer’s? Like 260 goals?” The mischievous laugh we caught a glimpse of at the start of the film returns.

Whilst it perhaps doesn’t hit too many emotional notes or personal insights, Haaland – The Big Decision is a treat for football fans – watch it now on Viaplay UK
