“Rangers might not do walking away – but they certainly do getting carried away.

“You’d be forgiven for thinking they’d won the Champions League at Celtic Park on Sunday given the way they celebrated. Don’t get me wrong.

“Rangers deserved to win. It was an impressive display, especially on the back of getting through to the Europa League last eight against Fenerbahce.

“But come off it – they walked off the pitch still 13 points behind Celtic in the Premiership.

“If we did that under Martin O’Neill he’d have had us straight up the tunnel and doing laps around Barrowfield all week.

“To be giving it the big one in front of their supporters on Sunday was some brass neck. It was only a few weeks ago the same fans were baying for blood.

“I know the result and performance meant something. I’m not being a killjoy, they deserve some bit of light after a horrendous domestic season.

“But have a bit of perspective.

“It goes back to what I’ve been saying most of this campaign. Rangers are a decent side but they have been mentally weak and it’s shown in some of their results.

“I’d have been kicking myself at full-time at the thought of beating Celtic twice in three games and still being so far back, certainly not celebrating.”
