Christian Pulisic made the £57million to Chelsea in January before being immediately loaned back to Borussia Dortmund until the end of the season.
The winger was highly sought after from a number of European clubs, with Jurgen Klopp’s Liverpool said to be a potential destination for Pulisic at one stage.
The United States international moved to Dortmund aged just 16 as one of the most promising talents in football, and has since gone on to make over 100 appearances for the Bundesliga side.
However Pulisic appears to have fallen out of favour slightly this season, having started just six league games for Dortmund, compared to his 25 Bundesliga starts during the 2017/18 campaign.
The American has featured 25 times for the Bundesliga side this season in all competitions, though, and looks set to feature for the USA once again in a friendly against Chile on Tuesday night.
Ahead of his move to Stamford Bridge this summer, we’ve identified five reasons why Pulisic can succeed at Chelsea.
Despite being just 20-years-old, Pulisic already has a wealth of first team experience in the Bundesliga and the Champions League after featuring over 100 times for the German side, meaning he will not be out of his depth at Stamford Bridge. The youngster also has the potential to improve a great deal in the future.
Chelsea's ageing wingers
With Willian and Pedro both entering the latter stages of their careers, the likes of Pulisic and Callum Hudson-Odoi will have the chance to push for first team spots given their potential.
Eden Hazard's uncertain future
Should Hazard depart for Real Madrid this summer, Pulisic will have the chance to assert his claim for the Belgian’s spot. The 20-year-old thrived while Marco Reus was injured at Dortmund, so the winger can clearly handle the pressure.
Partnership with Hudson-Odoi
With Pulisic only 20 and Hudson-Odoi 18-years-old, the pair have the potential to build a partnership together at Stamford Bridge.
Pulisic is incredibly quick, and the Blues have a history of succeeding with fast wingers in their side. The American has the ability to use his pace when both pressing and taking on opponents.
