The Owls reached the League Cup quarter-finals virtue of a wonderful display against Arsenal, defeating Arsene Wenger’s side 3-0 in-front of a packed out Hillsborough.
Commenting on the atmosphere and noise made the home supporters, Bannan admitted he had never heard anything quite like it and recalled telling his teammates how spectacular it was.
"The atmosphere was brilliant. Before the kick-off, I heard the fans singing and I remember looking at the other lads to say 'This is unbelievable,” he explained.
"I had never heard anything like it. When you have a crowd behind us, that isn't nice for visiting teams. It can frighten a lot of players.”
"Arsenal had a lot of young players that might have been taken aback by that. It is one of the best I have played in front of, definitely up there.”
Reasons to be cheerful
Since their relegation from the top flight at the beginning of the millennium, Wednesday have had very little to celebrate other than a promotion from League One and derby wins over Sheffield United.
It has been a real low point in the club’s other illustrious history, and crowd figures have dwindled.
However, under new owners and wise boss Carlos Carvalhal, the Owls are starting to find their feet once more and they headed into the Arsenal clash unbeaten in eight and well positioned in the table.
The football is good, the Championship playoffs are a realistic aim and the squad quality has improved.
After so many years of pain, Wednesday supporters had every reason to feel positive against the Gunners and the performance and ensuing result was no less than the hosts deserved.
