Loans just don't work well enough though, the hit rate on them is dreadful (not just for us, for everyone). You can even get them to go well and it means nothing in the grand scheme of things. For instance Tammy Abraham has had three loan spells, two good and one largely bad. What do Chelsea know now about him that they didn't know before? He can score goals in the Championship? Not very useful to them.
There's the utopia that he gets a full season somewhere that plays good football, gives him free reign to do his stuff, he plays nearly every game and really flourishes, finds his niche and comes back here an even better player. I would suggest that is very unlikely. Far more likely that he'd go somewhere and end up playing out wide or be stuck on the bench, wasting everyone's time.
Also given the size of our squad, if we let him go we'd have to sign someone else to replace him, which defeats the object really.
It's a solution that's constantly thrown around when it's very rarely appropriate.
