Is Paul Mitchell's exit from Tottenham indicative or wider problems or is he simply being tempted away?
Tottenham chairman Daniel Levy
Tottenham Hotspur were thrown a surprise days before the season opener with head of recruitment Paul Mitchell offering his resignation.
For a man in his position to push for an exit during a crucial phase of the transfer window is hardly a good sign, but what Tottenham need to be fearful of, is whether his departure signifies deeper troubles.
Tottenham have been regarded over the past 12 months as a model of a successfully run football club, achieving success on the pitch and financially prudent off it, developing young players with one of the best managers in football at the helm.

Even this summer they had bought well, signing Victor Wanyama and Vincent Janssen, although a deal for Georges-Kevin Nkoudou appears to have fallen through.
At Spurs Mitchell worked as part of a committee, with chairman Daniel Levy involved as well as ex-boss David Pleat, who pushed the deal for Dele Alli.

Tottenham are fortunate that Mitchell's resignation comes now rather than two months ago, before Mauricio Pochettino had signed his new contract, and was being linked with Manchester United.
Even despite the Argentine's deal, the fear is that Mitchell's exit will destabilise or upset him, given that he pushed so hard to bring him in from Southampton.
A Pochettino exit would be disastrous and potentially herald the exit of top players, so Tottenham cannot afford to have their head coach feeling annoyed with them in any shape.
Spurs are currently working towards the move in to their new stadium, and have until this point been a very stable club since Pochettino's appointment.
If he is 'annoyed' then Tottenham need to look at what they can do to keep him onside, whether this be more done deals now, shifting deadwood players, or bringing in a replacement for Mitchell, they should push to accomplish it as quickly as possible.
Tottenham are moving in the right direction, but they need to ensure this is merely a bump in the road and not a diversion which throws them off course.
