In northwest Germany, Pulisic is still just a kid, a foreign teenage recruit with a slightly exotic background working hard on turning regular game time - he's played 16 out of 17 league games and started four of out of six Champions League matches - into consistent end product in the shape of goals and assists. He is fast, has great technical and dribbling skills, and efficiently penetrates the opponent's defenses.
Pulisic recalled dabbling in basketball before he joined the Dortmund youth setup in 2015, though his 5-foot-8 frame always meant soccer was the more realistic career path.
"When you do that every week, you are going to improve. And thus I see Christian with us in the long-term". Even if Dortmund were prepared to sell him, which they aren't, he wouldn't be able to do what Coutinho had been doing for the team. I try to work on them throughout the week. This is a reality not shared by many top-level sides, who often have to remain patient against massed ranks. The emotion of playing Liverpool is often too much for young players to handle effectively.
Jose Mourinho has set his sights on securing a winger this season after the club's failure to complete a deal for Ivan Perisic.
Liverpool are known admirers of the 19-year-old and have attempted to lure him to the Premier League in previous years - they reportedly saw a £35m approach rebuffed last year - but Dortmund are understandably reluctant to part with their prized starlet, who has scored three goals in 15 Bundesliga appearances this season.
The inside view is that Pulisic could well be the USA's first soccer megastar - with all the commercial value that will bring.
His emergence as arguably the best-ever U.S. player will see him outgrow the confines in northwest Germany some time in his early 20s, at the latest.
"It's not about completely restarting".
