Does Europe have any fast growing cities?

We all know that the US, Japan, Canada and Australia have many fast growing cities(over 20% a decade). I have searched online for fast growing cities in Europe, but haven't found any. So my question to Europeans on this board is, are there any fast growing cities in Europe? Since the European population is set to decline sharply in the coming decades are there any growing cities at all or are most of the cities there just stagnant/declining in population? Or maybe there are some areas of Europe where cities are still growing fast?>
