Managers who treat their players the way Conte and Mou do burn through clubs very rapidly.
I don't think anyone else was watching the reserves game but the Spurs player was asking for it, there were other incidents leading up to that. Also they shouldn't change the rules just because a Liverpool player did something bad even though that's happened before. Lallana won't and shouldn't be banned from real games, and obviously he shouldn't have been sent off, but that wasn't the only thing that happened.
