Having seen all of our games and all of Spurs' games (bar a couple) I tend to agree with you here.
The reason why I think Lallana isn't mentioned in Sky's list or on Squwaka is his lack of key passes and chances created I guess. His defensive stats are also slightly worse than Eriksen's.
Personally I think he's been almost a revelation and over the course of Autumn he did deserve to get a mention ahead Eriksen (both of Coutinho and De Bruyne needs to be in there).
