Out-of-contract pair Paul Hartley and Jan Vennegoor of Hesselink have left Celtic confirmed boss Tony Mowbray. Mowbray said: "I had a good long conversation with Paul. He came in to see me.

"The outcome of that is Paul won't be offered a new contract. He is free to look for other employment.

"I have had no contact with Jan. Jan is out of contract - he is free to seek other employment and I'm pretty sure that's what he will be doing at the moment."
