I think they have pressure in Holland and Portugal too.
I really hope you're not right in your suspicion, although I've had the same thought. Unless they think he's done developing the other aspects of his game and just needs to learn how to mentally cope with physicality, it doesn't seem like a very smart approach to me. The fact he's being loaned out to a championship club and not to a club playing at a higher level doesn't exactly suggest he's done developing skill-wise.
If Amad is going to make it, it's not going to be because of his ability to handle the physical aspects of his game. So why don't we send him somewhere that will help him develop his potential in the things he does well. He can learn about Tuesday nights in Stoke later on. If indeed he needs that, after half a season in Scotland.
This all just gives me the same vibes as NHL teams burying skilled young european prospects in the AHL to help them "acclimatise to the North American game", despite the well-documented idiocy of that approach.
