In a remarkable development over the past 24 hours, reports emanating from Serbia appear to have been confirmed by the 33-year-old striker's representative Milan Calasan.
"It is true," Calasan told SPORT in his homeland. "(Arsene) Wenger told me he wants to bring Zigic to Arsenal.
"You cannot reject an offer like that. But Nikola must decide.
"Wenger is offering a contract until the end of the season with the option for another year.
"Arsenal want a quick deal, but Nikola has offers from Turkey and Switzerland."
However, Wenger insisted he would not panic buy in Giroud's absence, instead hinting that Lukas Podolski would stay at the club.
But it would leave Arsenal lacking a back-up target man, with Yaya Sanogo the only physical striker at the club in Giroud's absence.
The 6'8" Zigic is a free agent after being released by Birmingham City, where he was widely considered to have been a failure.
He has also played for Racing Santander, Valencia and Red Star Belgrade and is regarded as a strong but slow target man.
When the rumour circulated yesterday, it seemed like an ill-timed April's Fool. Zigic was highly rated when he arrived at Birmingham in 2010, but his stock fell alarmingly as he found goals difficult to come by at St Andrews.
Zigic became a scapegoat for wider issues at Birmingham, refusing to leave the club when they were relegated to the Championship, instead sitting on a big-money contract when the Blues were struggling to make ends meet.
He was widely expected to try his hand at a lower level, but agent Calasan does have strong links to Wenger - he was the Sporting Director at Grampus Eight when the Frenchman was the Japanese club's manager.
For all the mockery aimed at Arsenal for this reported signing, Zigic is free, experienced and has a decent goals record in Spain and for the Serbia national team.
But you have to wonder why bother at all - surely there is more value in giving Sanogo a run in the team and blooding a youngster in support, than in turning to a Championship reject coming to the end of his career?
