According to the Daily Mail, Sunderland have rejected the chance to sign trialist Chinedu Obasi on a permanent basis, due to concerns over his fitness.
New Black Cats boss Sam Allardyce will almost certainly be looking to add to his squad during the transfer window, but he may also consider signing a free agent immediately.
Former Nigerian international forward Chinedu Obasi, formerly of Hoffenheim and Schalke in Germany, has been training with the Black Cats in a bid to win a contract.
The 29-year-old is a free agent having left Schalke at the end of last season, but the big problem for the winger is that he suffered a broken leg earlier this year.
Proving his fitness has always been the priority for Obasi, but it seems that he hasn't been able to convince Allardyce that he will be able to make an instant impact.
The Daily Mail report that Obasi won't be signing for Sunderland on a free transfer, having failed to prove his fitness during his trial spell on Wearside.
Allardyce may now look elsewhere for a pacey winger to add some speed to his attack, with his former West Ham ace Ricardo Vaz Te still a free agent, and a possible alternative after Obasi seemingly failed to win a contract at the Stadium of Light.
