Sheffield Wednesday beat Arsenal 3-0 in the Capital One Cup on Tuesday evening.
The Owls picked up their finest win in recent years, by hammering Arsenal 3-0 in the Capital One Cup on Tuesday night.
And Bannan feels that Helan deserves a lot of credit for the performance he put in, with the Frenchman returned to Carlos Carvalhal's starting line-up.
“There was a little tweak with Jeremy [Helan] coming in and he caused all sorts of problems. I got put into the middle and I thought it worked," he said.
“We worked our socks off. When you get in teams’ faces as much as we did, it doesn’t matter how good the player is, they just don’t like it. That is what we did against Arsenal.”
Helan has had limited chances this season, with Carvalhal’s rotation policy seeing him drop out of the team on a regular basis.
The 23-year-old has made just six apperances in the Championship this term, but he has given Carvalhal a real selection dilemma for the weekend.
The Portuguese boss has one of the biggest squads in the second tier, and there are a number of players pushing for starting spots – with the side currently unbeaten in their last nine matches in all competitions.
Wednesday’s next match comes against Nottingham Forest at the weekend, and a win in that fixture could take them to the fringes of the play-off places.
