With nine games left to play in the Sky Bet Championship, Carlos Carvalhal says Wednesday will continue with the same methods that have proved successful all season.
The Owls have enjoyed a strong campaign so far and currently occupy a place in the coveted play-off positions.
Victory over Nottingham Forest on Saturday ensured Wednesday remained in the top six and although competition at the top is fierce, Carlos says no nerves will come into play.
“We win games with quality, not with nerves,” he said. “We don’t have nerves and think we must achieve this, we must achieve that.
“We just do what we like to do, play football, try to put quality on the pitch and try to win the games.
“We win the games by preparing very well, analysing the opponents, the strengths and weaknesses and try to create a good strategy.
“The players are the most important part of that because they must do it on the pitch. They are doing fantastic.”
That process continues on Saturday when the Owls host Charlton.
On the Addicks clash, he added: “Next game we will be against Charlton and this is the most important and we will be back again with full energy.”
