The Celtic man has been linked with a move away from the Scottish giants.
Celtic defender Efe Ambrose has played down speculation linking him with a move away from the Scottish champions, adding that he knows who is behind the rumours.
The 27-year-old centre-back has been linked with a switch away from Parkhead for much of the summer transfer window, with Olympiacos, according to The Record, weighing up a £1 million bid for the Nigerian.
It remains to be seen what manager Brendan Rodgers - who inherited Ambrose after replacing Ronny Deila in Glasgow this summer - wants to do with him, though the Northern Irishman has been fielding him in recent outings.
Celtic fans will not be shedding many tears if Ambrose were to leave, by virtue of his rather clumsy nature throughout his four-year stay at Paradise.
The Nigeria internatinoal, who has 51 caps for his country, was also linked with Bayer Leverkusen this summer, but the defender has cryptically suggested that an unspecified group of people are responsible for producing these rumours over his future.
Nevertheless, Ambrose, who has netted five times in his Celtic career, has insisted that he fully intends on staying with the Hoops in comments which will surely disappoint many of the club's supporters.
“I know the people who are behind these rumours, but I won’t mention them for now," he told The Scottish Sun. “I am not aware of any talks regarding a move away from Celtic. It’s the same people who were behind the interest from Bayer Leverkusen interest who are involved in this Olympiacos story.
“The perpetrators of the Bayer Leverkusen interest went as far as saying I told close friends they wanted to sign me. Meanwhile, I was alone training with the Celtic youth team, while the first team was in pre-season training in Slovenia and Austria.
“I have said before I am ready to fight for my spot in the team here, and nothing has changed."
