Ange Postecoglou has used the FA Cup third round shocks as a warning ahead of Celtic's trip to Hampden to face Kilmarnock.
The Premiership duo go head to head at the national stadium with a spot in the Viaplay Final up for grabs for the winner. The Hoops are the holders of the competition - previously known as the Premier Sports Cup - and will head to the south side of Glasgow as favourites to reach the showpiece event.
However, Postecoglou has pointed to the numerous weekend upsets down south in their domestic cup competition to emphasise that there is a different element to cup football. Both sides faced each other at Parkhead in the league last weekend with the Scottish champions running out 2-0 winners thanks to Jota and an Ash Taylor own goal. But the 57-year-old has warned that win counts for nothing ahead of Saturday evening. He told Celtic TV: “You just have to look at what happened down south in the FA Cup over the weekend and cup football in general, I’ve been around long enough to know that there’s always a different element to it.
