Besiktas are in talks to sign Nigeria midfielder Ogenyi Onazi from Lazio with representatives of the Turkish club travelling to Italy to complete the deal, a source close to the player has told ESPN FC.
Onazi is on the lookout for a new club following limited opportunities at the Rome-based Serie A club where he made only 11 appearances last season.
The source said Besiktas are one of three potential suitors for the midfielder, with a decision likely to be made by next week.
"He is weighing his options at the moment, but we should know better where he is going by the beginning of next week," the source said.
