I think it would have been fine to get Alli and Bergjwin off and bring PEH and Son on.
That way you get some control in the middle with PEH and you push Gio forward. Son on for that extra quality and Bergjwin's terrible performance.
Lloris
Aurier Sanchez Davies Reg
Winks PEH
Lo Celso
Bale Vini Son
I hate having to bring PEH on and would rather him resting for a full game, but given the options I think I agree.
I may have also taken Bale off for Lamela, but that likely is due to hindsight and seeing him do nothing in the 2nd half, at the time I likely would have kept him on hoping he would have found his form a little more in that half.
