This is all sorts of cheeky from Mario but at least he's not let off any more fireworks in his house.
We love a good derby, whether it be in North London, Glasgow or the North East. But while we're looking forward to seeing Big Sam vs Steve McClaren tomorrow, we all know which game really has our attention... the Manchester derby.
Now City are proper money bags, the Manchester derby's have become all sorts of exciting and very, very close to call – even for the two teams' managers.
While the players and coaches are keeping their cards pretty close to their chests, the two sets of fans are at their usual tactics or having a few digs at each other.
The Italian forward took to Instagram to post a somewhat mischievous photo which was enough to put a smile on City fans and get the United fans all sorts of mad.
Yep, Mario decided to post a picture of the time Man City thumped United 6-1 and he showed off that infamous 'Why always me' shirt to the world.
What do you think about Mario's post, pretty funny or just there to annoy fans? Either way, we're looking forward to seeing what happens tomorrow afternoon
