Just depends how they are played and in what position though. Dowell at minute is playing wide right in a midfield four. It's not his true position. Similarly a right full back playing as a wing back. Also depends on the footballing philosophy of the manager. If you've got all of that right then you can judge. Unfortunately it's been very hit and miss with our loans.If they don't excel in a lower league then they're unlikely to be ready to play at a higher level. That's not a hard and fast rule and there'll always be exceptions, but it's broadly true.
