Northern Ireland’s goalkeeping depth has not been as strong for a number of years, and there is a handful of further options who were either not selected for November’s game or were unavailable for selection.
The headline name is Conor Hazard, who has impressed for Wayne Rooney’s Plymouth Argyle but is out injured.
The 26-year-old has won eight caps, and would have likely made the squad if fit.
Mansfield Town’s Christy Pym was O’Neill’s third goalkeeping option for October’s matches when Peacock-Farrell and Hazard were both injured.
Pym, 29, is on the standby list for November’s double-header.
There are a couple of Under-21s options who could be names to look out for in the future, including Celtic’s Josh Clarke and 19-year-old Stephen McMullan, who is on loan at Caernarfon Town from Fleetwood Town.
