“After the game (Rangers against Hibernian) I had 47 text messages – all from down south – going on about the quality of the setting and the actual product,” Warburton told The Daily Record.
“Likewise, the Hearts-Celtic game – another packed stadium, quality football, great atmosphere and a late equaliser. Those games received a lot of approval in England."
