To which football club had Jamie Tartt transferred before Ted Lasso season 4?

Before Ted Lasso season 4, Jamie Tartt had transferred to FC Barcelona.

Jamie began the series as a talented but arrogant forward associated with AFC Richmond. Over time, he became a more cooperative and versatile player, developing his passing and playmaking as well as his scoring ability.

The season 4 character information states that Jamie had left Richmond and transferred to FC Barcelona before the season's events. The move explains why Jamie is not part of Ted's new women's-team coaching setup at the beginning of the season.

FC Barcelona is a real Spanish football club, while AFC Richmond is fictional. Jamie's earlier connection with Manchester City is another possible source of confusion: he was loaned to Richmond from Manchester City in season 1, but that is not his pre-season-4 club.
