because according to the player registration and eligibility requirements (4 homegrown, 4 association grown, 17 'free' slots are available), our squad is full, even if we don't have enough homegrown players. in order to sign ramsey, we have to sell someone. cuadrado is taking a place, injured or not. benatia's slot will be immediately filled by caceres. ramsey has no free slot up for grabs, we could only enter him to any competition in someone else's expense. so we either sell a guy or relegate him to the primavera - latter would be a rather expensive and stupid solution. so ultimately we'll have to sell someone to make room for ramsey.
