TWTD understands Sunderland goalkeeping-coach Jimmy Walker is set to join new boss Paul Lambert’s Town staff.
Walker, 45, played for Lambert during a loan spell at Colchester United during 2008/09, making 16 appearances.
The Sutton-in-Ashfield-born keeper began his playing career at Notts County before a long spell with Walsall where he made his name - making 404 of his total of 483 league starts plus two sub appearances - and secured a Bosman free move to West Ham in the summer of 2004.
Having played for the Hammers in play-off semi-finals against the Blues in his first season at Upton Park, he joined Tottenham in September 2009, before returning to Walsall - where he added another 50 league starts - prior to stints with Peterborough and Lincoln.
Walker, who is based in Stamford, began his coaching career with Posh in 2013 before moving on to Gillingham and then the Imps during their 2016/17 Vanarama National League championship campaign, in which they beat the Blues in the FA Cup, before joining new Sunderland manager Jack Ross's coaching staff in the summer.
Long-serving Town keeper-coach Malcolm Webster retired at the end of last season with head of academy goalkeeping Darren Smith, who had spent time working with the first team under Webster, given the role on what was effectively a trial basis by former boss Paul Hurst.
