The English winger has struggled to get many minutes on the pitch since Thomas Tuchel's arrival in January, and indeed since he initially broke through into the squad under the tenureship of Maurizio Sarri.
However, in a late twist, it appears that he may in fact be off abroad for the season - although it all depends on one important factor: whether the Blues allow him to go.
Goal has reported that, while a 'formal offer' is yet to be submitted by the German club, Dortmund have shown great interest in potentially bringing in the Wandsworth-born winger.
It is suggested that other major European sides are also observing the development of this late saga, implying that other major clubs may yet be the destination.
Such a move would not be unheard of whatsoever, with plenty of young English talents going to Germany to thrive in a youthful, attacking league that is the Bundesliga.
Additionally, players such as Reiss Nelson, Demarai Gray and even teammate Ethan Ampadu have enjoyed relatively successful spells on the continent, meaning the move may be seen as moderately attractive for Hudson-Odoi.
Tuchel remains firm
That said, while the interest is clearly there from overseas and it is obvious that Hudson-Odoi will not be a first choice, Tuchel has reportedly expressed a desire to keep the winger at the club this season.
According to Goal, the German head coach is strongly opposed to such a move, which suggests that more opportunities will be coming in this campaign for someone who is still a very young player.
Additionally, to willingly give up a player, albeit temporarily, that has amassed 78 G/A in just 160 games will always be done with a note of caution, meaning the delay is understandable on Chelsea's part.
Whatever ends up happening with regards to this summer though, it does appear at least partly certain that Hudson-Odoi's future at Stamford Bridge has something yet to be seen - something that a double European trophy-winning 20-year-old thoroughly deserves.
