With Mettomo out of contract he can be signed outside the transfer window. Norwich boss Peter Grant said the player would be a good addition to the squad having amassed considerable experience with former clubs St Etienne, Kaiserslautern and Manchester City, Norwich's opponents in the third round of the Carling Cup.
Grant also admitted, however, that Mettomo, 30, is severely lacking in match fitness. With the current injury list at Carrow Road, he'll be in good company, but the chance to recruit an international defender with Premier League experience for free may prove too good to turn down.
