The Belgian centre-half said: "We are a very disciplined team and have always shown an ability to react.
"Wednesday is a different game, a different set-up and it's important for us to win.
"When it comes to character, spirit and strength to overturn situations, there is no such thing as a one-man team.
"It's a very tough group, we always knew that. There are no easy games and it's very tight but it makes it more exciting."
