Carlos Carvalhal says his decisions in the transfer market were dictated by whether or not targets had Championship experience.
The Portuguese insists he was determined to forge a strong core of players with experience of English football’s second tier.
Carvalhal says it helped form decisions when choosing between targets ahead of last week’s transfer deadline.
And he is pleased with the balance in his squad of those with Championship experience and those without.
“All the time we are playing six or seven players that know the Championship,” Carvalhal said. “It is the majority of the team.
“It is the main group, I want them to feel they are very important to the team.
“They know the Championship, have experience of the Championship.
“This has happened because I try to care about that.
“It is one thing that sometimes makes a difference between choosing one player or another.
“It makes the difference. In the same conditions, I prefer the players that know very well the Championship, especially at this part of the season.”
Nine of the Owls’ 15 summer signings had previously played in the division with the rest coming to the club from abroad.
Wednesday failed to add a striker on deadline day after chasing several high-profile names with Championship experience.
Carvalhal admits it is difficult to find value due to inflated prices in English football.
He said: “Sometimes it is not easy to find the players with experience because the market is very expensive and sometimes the player we want is not available.
“As you know the market in England is very expensive.
“In the same situations, we also look to players from the outside like Marco Matias and Lucas Joao. We check these players.
“You understand the price and quality of the player is good and they can help the team.”
Defender Darryl Lachman - yet to appear in an Owls squad this season - started for Curacao in their 1-0 World Cup qualifying defeat to El Salvador on Saturday.
