He's only just turned 19, but Borussia Dortmund winger Christian Pulisic is already turning heads. After assured performance after assured performance on the domestic, European and international stage, bundesliga.com takes a closer look at the youngster who cannot stop breaking records.
When Pulisic stood on the pitch in Warsaw in September 2016, the UEFA Champions League anthem ringing in his ears, he was just minutes away from becoming Borussia Dortmund's youngest ever player in the competition. Yet far from being overwhelmed by the occasion, the 17-year-old American produced a man-of-the-match performance at the heart of the Dortmund attack, inspiring Thomas Tuchel's side to a crushing 6-0 victory over Legia Warszawa.
Anybody who had seen Pulisic in action in the preceding months would not have been surprised. He may be young, but he is, above all, extremely talented, which is what prompted Tuchel to promote him from the Dortmund U19s to the first team squad in January 2016.
Pulisic made his first Bundesliga appearance later that month, coming on for Adrian Ramos in a 2-0 win over Ingolstadt. Then, on 17 April, he became the youngest foreigner to score a goal in the Bundesliga, opening the scoring in a 3-0 victory over Hamburg. Six days later, he was on target in another 3-0 win, this time at VfB Stuttgart, becoming the youngest player of any nationality to score twice in the German top flight.
Pulisic's rapid rise through the ranks at Dortmund was mirrored on the international stage. Jürgen Klinsmann handed him his US national team debut in March – he came on a substitute against Guatemala in Columbus, Ohio, becoming the youngest American to play in a FIFA World Cup qualifier at the age of 17 years, six months and 12 days. He then found the back of the net on just his third appearance in a friendly against Bolivia on 29 May, becoming the USMNT's youngest modern goalscorer at 17 years eight months and 12 days.
The excitement around Pulisic – who has Croatian citizenship through his grandfather – is palpable. He made his first senior start for the USMNT on 7 September 2016, putting in another noteworthy performance against Trinidad and Tobago, and many consider him a natural successor to the USMNT's all-time leading scorer, Landon Donovan.
"We're delighted that Pulisic is doing so well for the USA," his former boss Tuchel said. "It's confirmation of his outstanding talent."
Watch: Christian Pulisic breaks another international record
In amongst those international records, Pulisic has continued to rack up the accolades even closer to his new European home. On his Champions League debut he became the youngest US player in history to appear and assist in the competition, and in March 2017 became the youngest American to score on Europe's top stage.
Before the 2016/17 season was out, the 18-year-old had gone one better than accolades and collected his first piece of silverware in the DFB Cup final victory over Eintracht Frankfurt.
