I don't think any defeats are acceptable! But I'm not going to isolate 4 games over the next 5 years. I do not think Silva is without fault, far from it, but we still have yet to field a healthy midfield and truth be told have no other options in the defense our midfield right now. Now if he continues to insist on the same XI, in the same formation, deploying the same tactics, I'm with you. It's not acceptable.
Start with dropping Gylfi that turd.
The mitigation concerning his midfield options is the only reason im not demanding he be sacked hourly like most.
I mean I would still sack him, but I can see why he hasnt been sacked.
