I'm so confused as to what some of the issues are here.
We went away to almost a full strength City (based on their current league team).
We rested half our team.
And.. we still barely loss and we played much better than them in the first half.
I haven't got issues with Arteta resting players. Turner, Tomi, Tierney, Vieira, Trossard all needed the minutes so that if they are needed in the league they're ready. The game showed why Sambi isn't the guy and probably never will be too.
Confused as to why there's any criticism?
Think the game showed that Holding and Sambi don't really have a big future here. I'd keep Holding around, but Sambi can be replaced by hopefully Caicedo and Patino next year. We need more from Vieira too, but happy to give him a year to acclimatise as he obviously has some talent. Trossard looked very good first half, him and Martinelli will be good competition.
