Newcastle United have moved for Arsenal defender Philippe Senderos.

The Mail on Sunday says Newcastle have made a shock bid for Senderos, increasing the growing tension between Arsene Wenger and his board over the continuing exodus of players.

Wenger was stunned when the offer of about £4million arrived on Wednesday and even more bemused when it was not rejected out of hand by the club.

Arsenal's board will hold out for about £6m, but their willingness to consider allowing another first-team squad member to leave after four high-profile departures this summer will alarm supporters and Wenger.
