Bryan Robson has been linked with the vacant manager's job at English first division side Crystal Palace following a hitch in his talks with the Nigerian Football Association (NFA).
Robson has been out of work since leaving Middlesbrough in 2001
Robson had been expected to be confirmed as Nigeria coach, but the move has been put on ice with the NFA struggling to meet the former England captain's wage demands.
"The situation with Nigeria is that it is not quite signed, sealed and delivered," Robson told the British newspaper The Guardian.
"My situation does not stop me from considering other offers."
He added: "I haven't heard anything from Palace so I can't comment on that."
Former Crystal Palace boss Steve Kember was sacked on Monday after a poor start to the season, with defender Kit Symons being placed in charge on a caretaker basis.
Robson had been expected to arrive in Nigeria on Monday to sign his contract and present his plans for next year's African Nations Cup to the NFA board and the media on Tuesday.
