Chelsea are playing real life Football Manager with Strasbourg.
They're fielding teams of almost exclusively young, highly rated prospects (starting 11 today had an average age of 20.8) and just chucking them in the deep end of men's football. If they swim they get a call up to the big leagues (Chelsea)
Ignoring the ethics - because everyone else does - it'd be interesting to do similar with Nice. It's undeniably smart on a football basis. Financially too. It'd also be entertaining, and useful, to watch Heaven, Kone, Lacey and Obi (Mainoo even) playing 40 games a season against Monaco, Lille and PSG instead of stagnating in the reserves, on the bench or enduring loans like Collyer where he plays 14 minutes a game or Amass where his team get battered every week.
