That’s despite Birmingham City’s goal in the 1-1 Championship draw at the John Smith’s Stadium coming from a free-kick.
The head coach admitted set-pieces proved a real problem in Town’s 5-0 defeat at Fulham but after only a second draw of the season (the first was also 1-1, at Aston Villa in August) Wagner said: “Why create a problem that isn’t there?
“We have had difficulty defending them in two games, Preston North End (where Town lost 3-1) and Fulham.
“But against Birmingham, I thought we were strong, and you have to look at the whole picture, 16 games so far.
“Conceding some set-piece goals is part of football.
“Show me a team who won’t concede to a set-piece over the season.”
