True but the tactics alone in a North London derby away from home is probably enough to get someone sacked, Carragher does a great analysis of Spurs midfield, or lack of one in that game. You could drive a Jose bus with a whole team through Spurs midfield with room to spare in that first half. You have Alli as a second striker and Ndombele as an AM, who are meant to be part of a midfield three. They are not taking up these positions just because they like that particular patch of grass on the pitch, it is clearly a tactical game plan by NES.
Then on top of this is the stats from Spurs this season, last in the league for shots on target, chances created, and km's travelled. They have also allowed the second most shots on their own goal, you can argue that the players need to take a look at themselves and that is most likely true, Spurs needed a clear out three years ago. But it is always the manager who walks, not the players.
