I don't think you will want to hear many of the answers.
In truth many of our players starting checking out mentally about around the Dortmund games run. Only Toby seemed to be stabile while Alli, Dembele and Lamela were in ascendancy. Then Alli went, then Dembele, Lamela plateaued while Toby crashed and burned, most notably yesterday. But in truth a whole lot of the others had been on their way down around then.
I said after the first Dortmund game, what I thought we *looked* in poor form, but got scythed down by the staticstics-brigade in an almost religious manner. I stand by that. Actually *watching* our games from then and on, it's been clear that our performances as a team and as individuals (a few names excluded) have been in steady decline.
I am not having a go at anyone, even though doing so could be well justified: I am just calling it as I see it, spectating the games and watching what is really going on out there.
