Celtic fans took to Twitter to destroy Mikael Lustig for his first-half performance in the Old Firm showdown against Rangers on Saturday lunchtime.
The Swedish defender, 31, was given the nod to start at right-back in a defence also featuring Dedryck Boyata, Kristoffer Ajer and Kieran Tierney.
Celtic dominated the opening period after Rangers had made an impressive start and the home side carved out a series of goalscoring opportunities at Parkhead.
But Lustig struggled to deal with the ferocity and pace of the encounter and made a series of errors in the first half, with his positioning and passing at fault.
Celtic supporters took to social media en masse to rip the experienced campaigner, who was making his 34th appearance of the season for the team, to shreds, with some claiming he is “past it” and “done”.

Lustig is absolute poison, on the other hand Tierney is excellent. Good pace to this game #OldFirmDerby
