Some Manchester United fans can expect a knock on the door from the local police after their antics on the weekend.

The Mirror reports a brave guerrilla army of Manchester United fans who visited the Eastlands area on Friday night to spray-paint local pubs with 'MUFC' ahead of yesterday's derby.

Unfortunately, the intellectually-challenged bunch have posted photos of their graffiti - together with messages inviting Blues to enjoy their handiwork - on their own Facebook pages. Which means they have virtually guaranteed themselves a visit from 'The Dibble' soon.
