Searching for a number within a text string

Hi, I have a list of customers and account numbers contained within a cell. I need a formula if possible that searches from the right of the cell and then returns the all the numbers.

e.g.

Arsenal1234 Required formula result 1234
Liverpool2456 Required formula result 2456
Chelsea100564 Required formula result 100564

I can not use text to columns as they data is not consistant.

Also worth noting is that the customer numbers vary fro 1 digit to 9 digits long.

Any help would be great
