Sheffield Wednesday insist they have done their homework on Huddersfield Town’s new boss David Wagner and are ready for the German’s first Championship match.
It was just over a fortnight ago Wagner, the former Borussia Dortmund coach, replaced Chris Powell at the helm.
The 47-year-old has been busy over the international break implementing the ideas behind the ‘gegenpressing’ system that he wants the Terriers to adopt.
Owls boss Carlos Carvalhal said: “We are ready to play, we know the opponent, but we don’t know the system they will play. They have a new coach and new ideas.
“The coaches are not magic. They cannot change everything in one week. I remember Jurgen Klopp (Liverpool boss) said to me after a game, that these kind of things, need months or years to change.
“Like he did at Borussia, he created a philosophy, but to create that takes years, not weeks.
“I expect changes, but to do the majority of ideas, create and implement a model, you need time.”
Daniel Pudil and Lucas Joao have returned from international duty unscathed but Sam Hutchinson is ruled out due to suspension.
Carvalhal said: “I am happy with what Sam is doing this season, he has played a lot of games compared with the past.
“He is doing 90 per cent of the training, so we don’t need to preserve him.
“I think he is happy too with the work and performances.
“Yellow cards? That’s the way he plays.
“It’s not red cards, they are yellow cards. I have other players to play in the position when he can’t play.
“We need him the way he plays, we need Sam like this. If he misses one or two games, becuase he has yellow cards, that’s not a problem to me.
“It’s a problem if he plays in a different way, and doesn’t play with the high intensity which we think he must play.”
