The Magpies have already signed French pair Yohan Cabaye and Sylvain Marveaux as well as Senegal international striker Demba Ba, while teenage midfielder Mehdi Abeid has also been recruited as one for the future.

more offensive
He said: "We have got to be diligent and patient.
"We are starting the season with five new players - Kevin [Nolan] obviously has gone - but we are in such a better position already.

The Magpies are monitoring Swansea City full-back Neil Taylor's situation from afar after the Welsh club rejected their £1m offer, a bid the Tyneside club believed triggered a release clause in the defender's contract.
