The Toon, through chief scout Graham Carr’s contacts, have made a succession of signings from France.

And they are now eyeing attacking-midfielder Grenier, 23, who is valued at about £10million.

The France international, who can operate wide on the right or behind a main striker, has attracted plenty of interest from England’s top flight.

Arsenal and Liverpool in particular have been linked with a move for him.

Newcastle are also expected to sign Montpellier midfielder Remy Cabella, also 23, in the summer.
