If the loan has an immediate recall option this makes sense. He could prove to be brilliant in which case we call him back and stick him in the first team.
If he’s not scoring lots he can stay there to ‘develop’ and get game time.
If it doesn’t have a recall option it’s madness.
He can't play for three different clubs in one season. If there IS a recall option it's madness.
Immediate recalls are gone (exceptions can be made for keepers). Can only be done in January.
