I have absolutely no problem at all in us not wanting to jump in & sign a unproven, raw Mo Barrow permanently without Rafa actually working with him first.
I reckon it's pretty clear right now that the club see this window as being built around trying to find players who they can loan for the sole reason of filling gaps if suspension/injuries occur and the fact that their enquiry for Barrow was apparently for loan only with no obligation to buy speaks volumes.
