This is just all sorts of cheeky from the young chap.
As we have seen from Arsenal fans and Cesc Fabregas, if a player leaves your club and ends up joining your rivals, there is a big chance that the fans really hate them now.
After joining City, Villa fans decided to call the England midfielder a 'snake', and during his first return to Villa Park, the fans showered him with boos and loads of plastic snakes.
So when Villa took on City in the FA Cup at the weekend, we expected a load of abuse from the Villa fans directed towards the City midfielder.
However, we were not quite prepared for the stunning abuse that Delph faced from Villa's mascot... just have a look at this:
OUCH! We are not sure Delph will every recover from such a burn by that young man, we reckon Villa fans will be very happy with that!
