SUNDERLAND fans have heaped misery on their greatest rivals – with a pair of comedy road signs mocking Newcastle United.

One sign, on the A184 leading into the city, has an arrow pointing towards Tyneside and reads: “Sid James’ Park, the biggest stadium in the ‘Fizzy Pop’ league’.”

The other, on the road to Sunderland, says: “The Stadium of Light, the North- East’s only Premier League stadium.”

A video of the stunt was posted on YouTube.

In it, one of the pranksters responsible laughs as the signs are revealed and says: ‘‘A little gift for our Newcastle friends. Our boys are doing the business. You little beauty, come on.”

Newcastle fan John Monaghan, 35, of Heaton, said: ‘‘They are entitled to laugh, after all we laughed at them when they were relegated in 2003 and 2006.

But it’s hard to find anything very funny at the moment if you’re a Newcastle fan.’’ Earlier this week, Black Cats fans made scores of bogus bids for United when the club asked for offers via email.
