Not going overboard with IB but, whilst there are some issues he managed to make the squad into a more exciting watch with little time so we should give him a fair chance.
As an interesting but generally useless stat his results for the first 8 games in charge match Warnock's (W 2, D 2, L4). I know stats can not be used in that way as a serious argument and Warnock's results did pick up quicker after that, but Warnock also had more time between matches to work on/with the squad.
