(Geometrical) centre (of something) is defined as a point from which everything else (of that something) is at equal distance... or from which everything (of that something) looks the same.
There is no centre of the universe, because it is the metric of the space-time that expands.
However, if we try to apply the above definition of centre to Universe, then the centre of universe is everywhere.... because Universe looks the same from every point inside it.
