I think our biggest asset this season is Neil Harris with the success that he has had in League 1 and the Championship, I just hope that he is / has been, able to bring in enough good players to achieve what his previous managerial success suggests that he should be able to.
Having been to the two home friendlies, I've seen some promising signs so far (Green and Williams the standouts from the new players from those two games for me), but I do think it somewhat depends on who the final few players are that Harris brings in this summer - From the sounds of his comments, at least some of them are longer term targets that he has been working on for a while, so hopefully this suggests they should be good quality signings.
All in all, if he can get those targets in, then I'd back Harris to guide us to a play-off spot (which is what I've voted for), and hopefully a Wembley promotion to follow!
