Meanwhile, Nottingham Forest were left incensed by a controversial intervention that denied them a victory. Neco Williams had a second-half goal ruled out for handball after Sandro Tonali's attempted clearance deflected off the Welshman.
Glasner heavily criticised the decision, stating: "So if we are guessing, VAR cannot intervene. It’s not clear and obvious and we were told before the season the threshold (for intervention) should be very high. We accept the point but it feels like we lost two."
Williams also defended himself, adding: "It's a goal. VAR is there when there is a clear and obvious error and for me that is not clear and obvious. I've seen the images and the replays and at not one moment did I think I handballed it."
