I'd hate for us to become like Watford and sack a manager just because the last few games have gone not according to plan. It would have to be a long losing run which carries on well into next season before that question should even be pondered.
I'd only rest Pontus, Bryan,Toney and Norgaard. I think Parker will play a weak side, because he will need his best eleven for the league games otherwise he will be facing the sack. A league cup loss will not factor into that.
