Take your miserable whining and fuck off.
Darker Days as in Tottenham's, not Jan bringing 'darkness'....TBF, I think Jan's "darker days" were over exaggerated then. He's had some dips in form, but so have many other players. Hugo has had some absolute blunders. Harry, Son, Dele have had long stretches of ineffective play before. Dembele didn't even look like much at first.
I think a lot of times we're far too quick to crucify players.
Personally, I defend out players to the hilt... I accept the concept of form as you rightfully note.
My concerns were of commitment/attitude. I don't think he was a happy bunny... Hence such an upturn from him when Toby arrived (I don't think of them like school kids so am generally reluctant to over-play their friendship, but a friendly face in times of struggle works wonders).
