Norwich keeper John Ruddy is being touted with a January transfer window move to Premier League Crystal Palace.

Ruddy is likely to be a regular feature in the transfer gossip columns ahead of next month's opening of the window, with Wednesday's Daily Mirror reporting Eagles' chief Neil Warnock is weighing up a move to test the Canaries' resolve to hang onto their number one.

The Palace boss wants serious competition for first choice Julian Speroni, with Ruddy on his watch list. The 28-year-old was heavily linked to Crystal Palace in the summer, along with Sunderland and Arsenal, before the England keeper publicly made it clear he wanted to stay and help the Canaries clinch Championship promotion.

Ruddy signed a new four-year deal in October 2013 after previous interest from Premier League title favourites Chelsea.

The Mirror claim City would not trade for less than £4m although chief executive David McNally reiterated on Monday during an online session with Norwich City fans the Canaries are under no pressure to sell against their will next month.

Palace is currently 15th in the Premier League table, a point above the bottom three, with Speroni an ever-present for the Eagles in the top flight this season.

Ruddy's form has come in for stiff criticism during a difficult spell for the Norwich prior to last weekend's Championship clean sheet in the 1-0 win at Wigan, with the ex-Everton keeper using his official Twitter account recently to underline his loyalty to the club after rejecting potentially more lucrative options to leave Carrow Road.

The Mirror also report his former club may look at Ruddy as a potential longer-term replacement for Toffees' number one, Tim Howard, at the end of this season.
