There are issues that need to be addressed, totally agree... Doesn't mean McInnes identified or even tried to sign anyone barring church and Tansey though. It's always difficult to get quality and value in January, maybe he just wanted to trust the squad he has and works with every day and wait for his first choice signings in the summer rather than signing players that would have been stopgap or 2nd/3rd choice signings.
He could have just as easily made a mess of the transfer window though, just putting forward an alternative view to the one that seems to be commonly accepted.
