Derry City have held talks with former Celtic player Willie McStay over the vacant manager's job at the Brandywell.
McStay, who was sacked after three months in charge of Ross County, is assistant manager at Stockport County.
He was manager at Sligo Rovers when they won a treble in 1993 and was reserve and youth coach at Celtic.
It is believed Jim Magilton has joined current Sligo boss Paul Cook in ruling himself out of the running to replace Stephen Kenny.
City approached Magilton, who is in contention to replace Phil Brown as Preston North End boss.
The former Ipswich Town and QPR manager Magilton recently missed out on the Northern Ireland job.
Magilton was assistant to new Northern Ireland manager O'Neill at Shamrock Rovers last season.
Following O'Neill's departure from the club, Kenny left Derry to manage the League of Ireland champions.
Cook had been given permission to speak to speak to the Brandywell club but a statement issued on Sligo FC's website has indicated that he will remain in his present post.
Derry City chairman Philip O'Doherty has declined to comment on the identity of the candidates expressing an interested in the vacant manager's job at the Brandywell, but said both he and the rest of the Board want a new man in charge as soon as possible.
"About 12 people have expressed an interest in becoming the new manager of Derry City but until we have something more than that, that's all I am prepared to say," O'Doherty told the Derry Journal.
