Aston Villa 4-2 Celtic: Analysis
When Aston Villa's Morgan Rogers scored twice inside the opening five minutes, you feared the worst for Celtic.
Villa's movement, their slick passing and the quickness of their play was scintillating and Celtic must have wondered what had hit them.
It could have knocked the stuffing out of them, but in fairness to the Scottish champions they grew into the match and started to get forward and create chances.
That seemed to give them belief, and from there they showed great character and resilience to get back into a game that looked lost. Adam Idah's brilliant finishes on 35 and 37 minutes came about after some superb build-up play from the visitors.
However, the home side upped the ante after the break and a third goal felt inevitable.
Despite taking a bit of confidence from Ollie Watkins' bizarre penalty miss, Celtic in the end were undone by Villa's quality, and overall the hosts deserved their win.
But Celtic can take heart from much of what they showed against an impressive side, and they'll take that into the Champions League play-off round.
