Today is a happy day, so as I said, won't caveat.
Interestingly I don't think Mason/Bentaleb or Dembele are critical to what I think I'm seeing
Critical to defense = Lloris, Jan, Toby (he's been worth his fee x2) and Dier in front
Critical to attack = Eriksen, Son (absolutely takes some of the attention off Kane, makes space), Kane
2 of Alli/Lamela/Mason/Chadli can almost be interchanged.
Clinton is a very interesting late game option, outball to a lot of pace, suspect he will influence a game or two this season
