Martin O’Neill is considering whether to remain Celtic manager after a damaging week that included two defeats by Rangers and a home loss to Ferencvaros. The 74-year-old, who returned as an emergency appointment and guided Celtic to the Scottish Premiership and Scottish Cup last season, said he would reflect on whether he still has the energy and ability to help the team.

Celtic remain top of the Premiership, but their recent performances have raised serious concerns. Their collapse against LASK in a Champions League play-off, narrow subsequent league wins and failures against Rangers and Ferencvaros have exposed weaknesses in the squad; pundits have also questioned whether summer recruitment added enough quality or depth. O’Neill plans to take time away and discuss his future with the board.
