Barry Bannan says the Owls showed fantastic team spirit on Saturday to restore their lead late in the game at Griffin Park.
Wednesday led 1-0 at the break through Atdhe Nuhiu’s penalty and had the numerical advantage following the dismissal of James Tarkowski during the same passage of play.
But having lost the one-goal lead and Jeremy Helan, who was dismissed after the break, the momentum swung in favour of the hosts.
But Wednesday dramatically regained their lead at the last through Lucas Joao and Bannan has praised the character of the squad.
He told swfc.co.uk: “I think we would have liked to play better but overall when you come to these places and take the three points it’s a big plus, so it was a good win.
“The momentum shifted after the break and being the home team, they were always going to have a spell in the game.
“Sometimes it can be harder to play against ten men and they caused us problems and fair play to them.
“We had the crowd behind us and we had to dig in.”
Bannan, who switched to left back following the dismissal of Helan, says it was tough defensively in the final 15 minutes and added:
“I played there before at Aston Villa. If you have got a good footballing brain you can slot in anywhere, so it was just about using your head.
“They were coming at us so it was tough in the end but I enjoyed it.
“Normally I’m an attacking player trying to make things happen but at Brentford I tried to stop the goals for the last 10-15 minutes.
“When Joao got his chance, I didn’t doubt he would score. He is a talented boy, he’s quick and he showed that today by getting away from the last man to score.
“I thought he shot a bit early but it was a great finish in the end and he took it really well.”
