Celtic showed a completely different level of intensity against Kilmarnock compared to their opening win over Dundee. Kasper Høgh scored after just 65 seconds and Celtic never looked back. Celtic’s 5.6 xG is the number that should really excite fansThe more impressive Opta number came from what Celtic produced over the full game. It was a major change from the opening win over Dundee, when plenty of possession produced far less threat. Celtic won’t post 5.6 xG every week.
