The prodigal son is returning. Well, at least one of them. Borussia Dortmund have had a whole bunch of prodigal sons over the last few years, perhaps more than any other club. Erling Haaland, Ousmane Dembele, Jude Bellingham, Jadon Sancho... it's a wild list.
This story, though, is about Christian Pulisic. Once a rising star at Dortmund, now a key figure at AC Milan. And, on Wednesday, Pulisic will return to Signal Iduna Park four years after he initially left the club in search of a next step.
That step came at Chelsea, but it was one full of highs and lows. It was one that produced a Champions League trophy, but it's also one that saw Pulisic's career stop and start more times than he can count. Despite the team's success, Pulisic's career at Chelsea never quite went the way everyone expected it to.
And that leads us here. Now a star with AC Milan, Pulisic is beginning to look like the player many knew he could be when he left Dortmund all those years ago, and he could play a key role as his current and former employers prepare for an absolutely humongous Champions League clash.
