Get on twitter and say that. They don't take kindly to anyone saying that...the retort will likely be "Enjoy league one", "Sad Mackem B...", "Paedo supporter" but never anything of substance. They came second twice in the 90's and last won the league in 20 something. Absolutely no credibility in any claim of "competing". Even when they were second it was 4 points (and a huge GD) and 8 points. It was hardly last day of the season stuff.
As a Newcastle supporter I don't believe we have any more right to compete than anyone else. However both of those seasons did go to the last day the first season we could still have won the league on the last day of the season if Middlesbrough beat Man Utd. Middlesbrough were comfortably beaten 3-0 and our game against Tottenham petered out and finished 1-1. The next season we were 5th or 6th going into the last day of the season and as we won the last game and those around us got beat we became the first club outside the Champions to qualify for the Champions League and Sunderland and Middlesbrough both got relegated on the same day. Although that one wasn't for the title it was a class day.
