Premier League referee Howard Webb appeared to be in a playful mood ahead of Manchester City's Capital One Cup clash against West Ham United.
The Yorkshireman was snapped 'photobombing' referee Jon Moss and his assistants before heading out to warm up prior to City's 6-0 win over the Hammers in the first leg of the semi-final.
Webb, who has returned to the South Yorkshire Police Force, was at the Etihad Stadium to perform as a fourth official for the clash.
City's media team caught Webb's 'photobomb' and posted it on their official Twitter page.
