Robinson has been targeted fill Celtic's problem left-back position

Celtic are believed to be in talks with West Bromwich Albion about luring their defender Paul Robinson to Parkhead.

Boss Gordon Strachan has identified the 29-year-old as the solution to his problem left-back position, with Lee Naylor looking to return to England.

Robinson enters the final year of his contract at The Hawthorns and is frustrated at the lack of a new deal.

Wigan tried to sign the player in a �1.5m transfer last year but the move collapsed after he failed a medical.

Robinson went on to play a vital role in helping Tony Mowbray's side win the Championship, and was even named in the team of the year for that division.

Celtic could snap up the full-back at a lower price if he fails to agree a contract extension with the Premiership newcomers.

Robinson, who started his career at Watford, has earned a reputation as a versatile, no-nonsense defender able to slot into a number of positions at the back.

Current first-choice left-back Naylor enjoyed an impressive debut season at Celtic Park after joining from Wolves in August 2006 for �600,000.

But his form dipped last term and Strachan is thought to be ready to offload the 28-year-old.
