Daniel Pudil says he sees similarities between Wednesday and the Watford team who gained promotion to the Premier League last season.
The left-back featured prominently in the Hornets side who finished runners up to Bournemouth last May.
Pudil, on a season long-loan deal from Watford, said: “When I went to Watford, I think we only won a couple of the first 15 games and struggled in the first part of the season. But then everything settled down and we won a lot of games in a row and we pushed up in the table. It is the same here. Everything has settled down and we have played well.
“We have a big squad. Everyone can play right now because we have a strong squad. We all good friends. Even if someone is not playing, we are still supporting each other.”
The 30-year-old feels Wednesday possess the strength in depth to compete in the upper echelons of the division.
“There is big potential in this team,” he said. “It is very important that you have more than 11 or 12 players who can play.
“If you have 20-25 then you know if you have injuries or suspensions, you can bring somebody in and they will play well. In this league, you need a big squad or you are struggling as you can’t play the same eleven.
“That’s what made the difference for Watford because it is so tight in the league.
“We have quality in the squad and that’s good because the Championship is hard. It is a long season so you need a big squad.”
Pudil may get the opportunity to add to his 27 international caps next week, having been included in Czech Republic’s senior squad for the first time since November 2014.
“I got the email and the manager phoned me and asked me if I was okay and not injured after the Arsenal game,” he said.
“I am happy to be back as I haven’t been in the squad for a year due to not playing enough games at Watford.
“My first ambition was to play for Sheffield Wednesday and do the best for the club and that was the most important thing.
“But now I will go there with good confidence and hopefully I can show my potential and be in the squad for 2016 European Championships.”
It has been a hectic period in Pudil’s life, with his girlfriend recently giving birth to their second child. Daughter Ella was born just hours before the win over Preston North End, with Pudil playing and scoring.
If that wasn’t enough, Pudil has also moved into a new house with his family and found a school for his young son.
“Things are going well and I am happy and enjoying being here,” he said. “I am playing games again and my family have settled down easily in the area.”
