Chief executive Peter Lawwell insists Celtic will not get involved in a spat with Rangers after the Ibrox club accused the Parkhead support of a “sickening and shameful display of outright sectarian hatred”.

Controversy was sparked during Saturday’s Old Firm duel when the home support hung effigies up from the Celtic Park stands.

Light Blues chiefs have now promised to hold talks with official supporter group Club 1872 after they called for the entire Hoops faithful to be barred from Ibrox when the teams next meet.

The weekend Premiership showdown was Rangers’ first league visit to Celtic Park in four years and saw Brendan Rodgers’s men romp to an impressive 5-1 triumph.

But the match has been overshadowed by events on the terraces.

Underneath a banner reading, “This is it Bhoys, this is war”, two blow-up dolls – one wearing a Rangers scarf, the other an Orange sash – with nooses wrapped round their necks and arms tied behind their backs were strung up from the upper tier.

Rangers officials said they shared the “disgust” felt by their fans following the shocking display but now Hoops chief Lawwell has insisted he will deal with the issue behind closed doors.

“What we won’t do is to get into a public spat or tit-for-tat situation,” he said.

“We try to operate to the highest possible standards.

“We will deal with these matters as we always do in a professional and private manner.”
