Not a bright idea, if you think there is spare land around the Etihad stadium you really are man united blinkered
Manchester city have the biggest investment in that area, try looking around or searching on the internet.
Now if your looking to make a permanent memorial to fergie, why not do what they did for matt busby, no not a statue out side theater of day dreamers, he has one. Not a road named after him, we don't need another road with a stupid name, so why not give him the same as matt busby and buy a burial plot in Southern cemetery for him, you might be lucky and get the plot next to matt's . That way he will have done the treble just like busby did
And the subject of the threat is labeled "A Fitting Farewell to Fergie" after all
