they have more than 20 players out on loan, it's ridiculous, lukaku may go out on loan next season, courtois has been on loan at atletico for 3 seasons now, Loaning all these players out is 1 clever way of getting around the homegrown rule which lukaku will be classed as of next season despite playing only 10 games at chelsea.
It's obscene. 27 players on loan, including three to separate Prem clubs and no less than five different Championship clubs have Chelsea players playing for them.
Around ten seems to be the norm for mos clubs - Liverpool have 14 and it looks like they might be the next-most.
