Watch: Mourinho brushes off Chelsea signature seeker

New Manchester United manager Jose Mourinho is no stranger to the Premier League, what with his best days coming at the helm of Chelsea, after all.

It's why this video of Mourinho disapprovingly shaking his head and smirking is particularly irksome to Blues fans, as Mourinho, just barely a Red Devil himself, bemoans a Chelsea fan looking for a signature.

While Mourinho looks to at least concede a quick scribble with his marker, it's a little heartbreaking to see just how quickly he has moved on from his former club.
