Liverpool have officially submitted a bid for 17-year-old Borussia Dortmund forward Christian Pulisic thought to be in the region of £11 million.
The highly-rated American broke into Thomas Tuchel's first-team at the back end of last season, scoring twice in 12 appearances in the Bundesliga and Europa League as well as grabbing two goals in their recent pre-season.
Having also scored on his international debut for the United States, the attacking midfielder - who can also play out wide - has attracted interest from Premier League rivals Stoke City with Bundesliga newcomers Red Bull Salzburg also thought to be interested.
Stoke are thought to have made a similar offer to Liverpool's, prompting Jürgen Klopp to follow up with an offer after Pulisic signed for Dortmund when he was manager at the Signal Iduna Park.
The teenager is the youngest non-German ever to score in the first division after scoring against Hamburg back in April and is among Dortmund's brightest young talents, appearing against the Merseyside outfit in the Europa League last term.
But Tuchel has brought in Andre Schurrle, Mario Gotze, Ousmane Dembele and Emre Mor in attacking positions over the summer, limiting the possibility of regular first-team football for Pulisic in 2016-17.
Klopp keen on reunion with promising US starlet
Pulisic played for Dortmund's Under-17s while Klopp was at the club after signing for the club in January 2015, before the current Reds boss promoted him to the first-team just five months later.
He made his senior debut in February and his reputation has only risen since, which will make it difficult for the Reds to iron out a deal with Dortmund.
Klopp is keen on reuniting with Pulisic, as shown by the size of their opening offer for a player so young in his progression, but his immense potential will make it difficult to conclude any deal before the closure of the summer transfer window.
The Yellow and Blacks are intent that Pulisic is not for sale at any price, though their first offer would make him the most expensive teenage signing in Liverpool's history as well as one of the most experience Americans.
Pulisic, also the youngest player in the modern era to score a goal for the United States after netting against Bolivia at 17 years 253 days old, would seemingly fit the mould of an archetypal Klopp forward.
His qualities on and off of the ball align with what the German expects of his forwards, with obvious room for improvement given his career is in its infancy.
It is that which Klopp believes makes Pulisic such an exciting addition, with the Pennsylvania-born USA international seen as one for now and one for the future simultaneously.
But it is expected the Reds will not only have to use their best persuasive tactics to convince Dortmund to do business, they will also have to up their offer, with their first bid likely to be firmly rejected.
