I think people fail to realise the level of legendary status afforded to Ole at OT.
As far as I can recall/am aware, there's a Ryan Giggs banner, a George Best banner and the 20LEGEND banner up on the Stretford End. Maybe that has changed as I haven't been regularly now for 3/4 years, but for a long time, Ole was the only player I can think of who had a full-time banner dedicated to them in the stadium. Nothing for Keane, Scholes, Rooney, Ronaldo, Schmeichel, Beckham, Ferdinand etc....
Point is, we have loads of "legends" at Utd because we have such a rich History, however, there are probably only a few who have achieved "elite" status, and I would say Ole is in that bracket.
I think this is often missed by the media and even some of our own fans who maybe for whatever reason haven't been to OT regularly.
