Celtic boss Neil Lennon admits there's huge interest in Efe Ambrose.

The Nigeria defender has Sunderland, Liverpool and Swansea City tracking him.

Lenny said: "Efe has got a few admirers out there now on the back of his performances this season. There has still been nothing concrete but I've been made aware of it - put it that way.

"There is interest from top teams.

"He has been a great signing for us. He's also brought the best out of Kelvin Wilson, who has been really magnificent.

"At European level they have made us better."
