The 41-year-old made a rather off-the-cuff announcement following his team's 1-0 League Cup defeat.
The Blues have been in good form in the new season, losing just one of their first seven games in the Championship. However, it seems that they might have had something of a helping hand ahead of last night's fixture at Villa Park.
Speaking after the game, Birmingham manager Gary Rowett dropped a surprising declaration when he claimed that he knew what Aston Villa's line-up would be 24 hours before the game kicked off.
As reported by Eurosport, Rowett said: "I actually knew their team yesterday funnily enough, and we did a little bit of work against it, got some runners into some great positions first half.
"That often happens - you often get a little tip off. Sometimes they're right, sometimes they're not. We haven't chased that."
Opposite number Tim Sherwood did play the leak down following Rowett's words, but appeared confused as to why the Birmingham boss would reveal such a thing once the contest was all said and done.
"Well done. Of course it's not (worrying). Did he tell you who it was?," Sherwood said. "It's interesting why he even mentioned it. It's strange."
The fact remains that Aston Villa have progressed to the next round of the Capital One Cup, which is a timely boost given their lacklustre start to the new Premier League campaign.
Sherwood's team have won just one of their opening six games in the new season, and currently reside just a point above the relegation zone in 17th place.
