Haaland vs Mbappé at age 19

Haaland at 19: the Salzburg autumn

Haaland turned 19 on 21 July 2019, two days after a hat-trick against Parndorf in the Austrian Cup, and spent the next five months scoring at a rate nobody in European football could match. He scored 16 goals in 14 Austrian Bundesliga games, 4 in 2 cup ties and 8 in 6 Champions League group matches: 28 goals in 22 games for Salzburg, with 5 hat-tricks, before Dortmund paid his €20m release clause on 29 December 2019. He was named Austrian Bundesliga Player of the Season for a campaign he left at the halfway point, and the Kronen Zeitung's Austrian Footballer of the Year for 2019. Salzburg went on to win the league and cup without him; the dataset credits him with neither, which is why the trophy row reads 0 to 3.

Seven goals in three Bundesliga games

His Dortmund debut on 18 January 2020 is still the most famous of the modern Bundesliga: a 23-minute hat-trick from the bench at Augsburg that turned a 3-1 deficit into a 5-3 win. Two more goals as a substitute against Köln a week later and two against Union Berlin on 1 February made it seven in his first three league games, and he was the Bundesliga's Player of the Month for January. He finished with 13 league goals in 15 appearances, a goal every 81.6 minutes, as Dortmund finished second to Bayern, plus one in the DFB-Pokal defeat at Werder Bremen and 2 in the Champions League. Across the two clubs the season came to 44 goals in 40 games, 1.10 per game, the first of the goal-a-game seasons that have defined his career. Mbappé's rate in Paris, 0.46 per game, was lower than his Monaco figure of the year before, because he spent the season on the right of a front three built around Neymar and Edinson Cavani.

Mbappé at 19: €180m, a treble and 15 assists

Mbappé began 2017-18 as a Monaco player, losing the Trophée des Champions to PSG on 29 July and playing one Ligue 1 match against Toulouse on 4 August, and ended it as the most expensive teenager in history. He joined PSG on deadline day, 31 August 2017, on a loan with an obligation to buy for €180m, scored on his debut at Metz on 8 September and scored again in his first Champions League game for the club at Celtic four days later. The season's return was 21 goals and 15 assists in 44 games for PSG: 13 goals and 8 assists in Ligue 1, 4 goals in the Coupe de France and 4 in the Champions League. PSG won the league by 13 points and both domestic cups, so he collected 3 team trophies to Haaland's 0, and he retained the Ligue 1 Young Player of the Year award and collected the 2017 Golden Boy in December. His 15 assists are a column Haaland cannot answer: the dataset has no verified assist figure for Haaland's Austrian or German league seasons, only the one Champions League assist.

Champions League: ten goals each, and the first meeting

Both players reached ten career Champions League goals during these seasons. Mbappé's tenth came at Bayern Munich on 5 December 2017, fifteen days before his 19th birthday, the youngest player to reach the mark; his 4 goals that season all came in the group stage, against Celtic twice, Anderlecht and Bayern, and PSG went out to Real Madrid in the round of 16 without a goal from him in either leg. Haaland's 10 came in a single season: a first-half hat-trick on his debut against Genk on 17 September 2019, goals at Anfield and home and away against Napoli, a fifth consecutive scoring game at Genk that made him the first teenager to score in five Champions League matches in a row, and then two for Dortmund against PSG on 18 February 2020, which took him to ten at 19 years and 212 days, the second-youngest after Mbappé. That Dortmund v PSG tie was also the first time the two had faced each other: Haaland's two goals won the first leg 2-1, Mbappé set up Neymar's equaliser, and PSG won the return 2-0 in an empty Parc des Princes to go through. Both matches are itemised above.

The shooting numbers: a finisher and a creator

Understat has Mbappé's full Ligue 1 season but only Haaland's Bundesliga half, so the shooting rows compare 2,173 minutes with 1,061. Haaland scored 13 from 8.89 expected goals, an overperformance of +4.11, and scored 10 of his 13 big chances (76.9%). Mbappé scored 13 from 14.31, -1.31, and 8 of 18 big chances (44.4%), but took more shots (3.31 per 90 to 2.80) and did far more of the creating: 8.79 expected assists and 2.15 key passes per 90 against Haaland's 1.53 and 0.76. Neither scored a league penalty in these seasons. The pattern of the two careers is already set here: Haaland the pure finisher at 81.6 minutes a goal, Mbappé the wide forward whose goals come with assists attached.

International football: a Norway debut, a World Cup

Haaland's senior Norway debut came against Malta on 5 September 2019, six weeks after his 19th birthday; he won 2 caps in 2019 without scoring, and the 6 goals in 5 caps shown for 2020 all came from September 2020 onwards, when he was 20. Mbappé's 2017 figures, 10 caps and 1 goal, include his first France goal against the Netherlands on 31 August 2017, the day his PSG move was confirmed, and his first World Cup qualifiers. Then came 2018: 18 caps, 9 goals, and the World Cup. Mbappé scored four times in Russia, two of them in the 4-3 win over Argentina and one in the final against Croatia on 15 July 2018, at 19 years and 207 days the second teenager after Pelé to score in a World Cup final, and was named the tournament's best young player. The final fell 15 days after his age-19 club window closed, so the medal and the awards that followed it are counted with his 2018-19 season, which will have an age-20 page of its own, but he was 19 when he won it. The Ballon d'Or that judged the season placed him fourth in December 2018; the 2020 ceremony that would have judged Haaland's was cancelled.

Verdict: Haaland's goals, Mbappé's medals

On goals it is not close. Haaland scored 44 to Mbappé's 21, more than doubled him in the Champions League (10 to 4), scored 6 hat-tricks to none and turned a running-total deficit of 6 at the end of the age-18 seasons into a lead of 17. On everything else it is Mbappé: 15 assists, three domestic trophies, a Champions League round of 16 reached with a club that expected more, fourth in the Ballon d'Or, and a World Cup winner's medal won at 19 and recorded on the next page. The same-age comparison follows the running total through every age, and the goals-by-age article picks the story up at 20, when both scored around 40.
