Not satisfied with giving us nothing all season, the winger now believes that we should see no return for our £10million investment four years ago.
Robert, 30, has hinted that many Premiership clubs are interested in his services and that he would prefer to stay in England.
Graeme Souness will be looking to receive at least £3million for the under-performing former PSG man, with Man.City a potential suitor.
Robert has thrilled the Geordie crowd on many occassions during his stay on Tyneside but has been ineffective in the majority of games this campaign.
