I'm not sure Aspas will / can be sold - not because we don't want to, but because interest is probably low. I think it's more likely he gets loaned out for a season first as his scouting report last season would've been pretty shit. Why not try before buying if they could, since the queue would probably be pretty short for him?
Ditto for Kelly. I know Rodgers has said he'll get minutes but I take that at just face value. Again, he hasn't kicked a ball enough times in two seasons to warrant a club shelling out money for him, so a try-before-buy deal is more likely.
Might work well for us too - look at Borini for example. Had we sold him a season ago, he'd not be worth the 10m or 12m being quoted / demanded now. A season later, we're talking about potentially recouping the sum we paid for him. Same thing for Assaidi - one season out on loan when he's done okay, and now we're asking for 5m to 7m, which is a profit of a few million for us.
