Bristol City's aerial weaknesses were exposed on Tuesday when Luton undeservedly snatched three points following two innocuous set-pieces.
Manager Nigel Pearson highlighted the issue as the club's "Achilles heel" which could explain the reasoning why the Robins have signed 6ft 4" defender Timm Klose on a free transfer, with the Swiss international agreeing a deal until the end of the season.
Klose, 33, has been on trial since last Friday and watched Bristol City Under-23's in action on Tuesday afternoon as he gained accustomed to his surroundings while taking note of the rising talent coming through the youth set-up.
