Do you seriously think Tony would have let us bobble around in League 1 for 5 seasons ?Like Paul Ince or Jim Gannon?
Gus took us from the relegation zone in League 1 to 11th in 6 months. The following season we went top in September breaking all our previous records of weeks at number 1 spot, winning 8 games out of 8 in March 2011, and winning the title with a record 95 points.
His first season in the Championship saw us in the top ten, with a lot of League 1 players, he was saddled with because of appearance clauses which gave them another year's contract. Then he tried to get some of his own players in (succeeding with Vicente and Ulloa) but finding other blocked by Burke & Barber, but still got us to the playoffs.
Yes, it all went wrong but it took 3.5 years to go wrong. Most managerial posts last 18 months.
I'm glad we have Chris Hughton now but don't rewrite history. He made mistakes, the club made mistakes but it was fun while it lasted.

No, someone who could have taken us up would have been appointed.
