RANGERS legend says there would be carnage if his sons decided to support Celtic.

The Ibrox hero joked that his boys wouldn't be welcome home if they swapped their allegiances.

McCoist's boys support Rangers, much like their old man.

Speaking on talkSPORT, McCoist was reacting to news that Dean SMith's son, who on return from the US opted to go to Anfield with the Aston Villa away support rather than watch dad’s team against Manchester United.

That moved on to David Beckham - whose son Romeo opted to support Arsenal over Manchester United, where his dad is so famous for playing.

Darren Bent asked how McCoist would be if one of his sons wanted to support Celtic instead of Rangers.

McCoist told thebreakfast show: “I love David Beckham but my sons would not be allowed back in the house if they didn’t support the world famous Glasgow Rangers.

“Seriously? That would cause carnage!

“Their Premier League team is Chelsea but my youngest has taken a shine to Leeds. But he told me the other day that Chelsea is still his first team.”
