Lee McCulloch believes Celtic players will be "banging their heads against the wall" after missing a series of chances in the Old Firm derby at Parkhead to reduce Rangers' seven-point lead at the top of the Clydesdale Bank Premier League.
The Ibrox midfielder headed a vital equaliser two minutes after Celtic substitute Scott McDonald had nodded the home side into a 79th-minute lead.
However, all that drama came after the hosts had squandered a series of chances as well as having a goal chalked off in the first half by Old Firm debutant referee Steve Conroy, who adjudged Marc-Antoine Fortune to have fouled Gers keeper Allan McGregor in an aerial challenge.
McCulloch acknowledged the pressure Rangers had been put under for most of the afternoon.
"They will be banging their heads against the wall thinking 'why did we not win that game?'" he said.
"I played in the France games for Scotland and we got battered but still came away winning.
"That's football. You get that and you need to move on.
"It showed great character for us to come back into the game and grab the goal and hang on in the end.
"Maybe we lacked a little bit of belief but we will take that point and move on.
"We have to realise that we weren't good enough as a team but we managed to get that point and we will keep going for the rest of the games."
McCulloch added: "I hope it does a lot (of psychological damage to Celtic's title hopes).
"I don't know how much time was left when they scored but their players and crowd got a lift from it.
"That's when we started to come into the game and maybe it was only going to be a set-piece that we would score from but the goal could go a long way as we come to the most important part of the season."
