I think everyone is looking for the next Pochettino, to come in from a smaller club and produce the goods at a higher level. It is however rare for a manager to step up in the way that he did/has.
If we want to compete at the top (or indeed just start competing at all), we need to bring in a manager who is already at the top level. Otherwise, I fear we will be forever searching for that special one who can step up to the plate.
