West Bromwich Albion report back to pre-season training today with Kanu's agent warning he is unlikely to return to The Hawthorns.
Bryan Robson welcomes his squad, including new signings John Hartson and Chris Perry, back to their Walsall training base but Kanu will be conspicuous by his absence.
Kanu was one of three players offered new deals after their relegation from the Premiership last term.
Kevin Campbell's future is still unresolved although Albion are optimistic Steve Watson will sign a new deal by the end of this week.
Kanu's agent however is adamant he has played his last game for Albion.
"Kanu is in Nigeria and I don't think he will be coming back to England," said his agent Barry Silkman.
"There are a couple of offers but nothing exciting enough for him."
The news will not come as a surprise to Robson who was preparing himself for this scenario from the moment their relegation was confirmed.
Speaking at the end of May, Robson admitted the likelihood of the 29-year-old Nigerian international staying at The Hawthorns was slim.
"Kanu is very doubtful because of the wages he was on," confirmed Robson.
"We can't offer those wages in the Championship, that's a fact.
"So it's up to Kanu, whether he's prepared to drop a lot in wages and wants the challenge of staying at the club, or he wants a move elsewhere."
With Hartson and Nathan Ellington expected to spearhead Albion's promotion charge this season, Kanu's departure is inevitable. While Robson recognises his talent the slog of a Championship season was always going to be a barrier and he will take solace in the news that Watson is on the brink of signing his revised deal.
If Kanu has played his last game for the club however, supporters will remember him with affection.
A record of nine goals from 42 starting appearances belies his talismanic qualities and a virtuoso performance against Tottenham Hotspur last December will live long in the memory.
He led their defence a merry dance and scored two exquisite goals before hoisting ball boys Kieran Day and Mark Hingley aloft.
His silken touch shone out like a beacon last season and his affable demeanour also endeared him. Yet his departure could free up more funds for Robson to increase his already healthy squad.
