You think Kane (and every other player) doesn't know we should be beating Sheffield?
The main problem with Poch is when you look at all the players who seem to have a problem with him (Toby, Jan, Eriksen, Rose, Sissoko, Kane, etc.), there isn't one young player there. If most of the experienced players are seeing something wrong, are seeing the results go sideways and are not seeing the leadership to help change it .. who is the problem?
Maybe they see bad/late subs, see tactics not work week in, week out, lack of merit/form based selections, experienced players freezed out when they disagree.
Honestly, I hope if Kane really feels that, he goes to Levy
