His former partner in the Republic of Ireland engine room, Mark Kinsella, probably isn't as renowned for his ability to melt ice with his eyes.
However the Drogheda United assistant manager was having absolutely none of a United Park's steward's decision to ruffle his hair as he took his seat during the Louth Derby on Friday.
