Yahoo Sports reports: Former Celtic striker Darren Jackson is "surprised and disappointed" Martin O'Neill's backroom team is yet to be confirmed following his appointment as permanent manager. Shaun Maloney and Mark Fotheringham were key lieutenants as O'Neill guided Celtic to the title and Scottish Cup last season, but have reportedly been asked to take a pay cut to stay on. Gavin Strachan, Stephen McManus and goalkeeper coach Stevie Woods were also part of the backroom team that delivered Celtic's fifth consecutive league title.
