The Belgian Pro League side only got promoted to the top tier last season.
They have had the likes of Kevin De Bruyne, Romelu Lukaku and Thorgan Hazard at the club, all sold for a meaty profit.
Now it looks like more could be on the way.
Reports in Belgium today, including one from Walfoot, suggest that Chelsea have agreed a partnership with Belgian Pro League side Royal Mouscron-Peruwelz.
Similar to their deal with Vitesse Arnhem the move will see plenty of Chelsea players head out on loan to Mouscron. Meanwhile, any top talents at the club could find themselves on their way to Stamford Bridge - much like Marco Van Ginkel did with Vitesse.
Mouscron recently agreed a similar deal with French side Lille and, in fact, the majority of their current team is in fact French.
They formed from former Belgian sides Excelsior Mouscron and Peruwelz - who both went bankrupt in 2009.
Now they are currently looking forward to a second season in Belgium's top tier, with a lucrative deal apparently in place with one of Europe's top club sides.
