Moore guided Sheffield Wednesday back to the Championship last season but parted ways with the club after a disagreement with owner Dejphon Chansiri before the beginning of the new season.
Sheffield Wednesday appointed Xisco Munoz as his replacement, but under the Spaniard, the Owls sit at the bottom of the league table.
Parkin stressed that it was a poor decision by Sheffield Wednesday to appoint Munoz as their manager and believes that the bond Moore built with the Owls faithful has collapsed with his departure.
He believes that the club need someone who knows the squad and fanbase more than ever now and stated that Sheffield Wednesday should have stuck with Moore.
“We have been critical at times of Darren Moore, but that steadying influence of that bond that he seems to have had with supporters now seems to have left a huge gap really at Sheffield Wednesday”, Parkin said on the What The EFL podcast.
“If ever they needed someone who knew the squad and knew the supporter base, it is now.
“[Munoz] looks like a really bad appointment.
“Sticking with Darren Moore and having the continuity of him working with the players, it is not a brilliant squad and it was not going to be like Ipswich, going up to the Championship, probably not even what Plymouth Argyle would achieve this year, but he probably would have kept them in the division.”
Sheffield Wednesday have yet to win their first league game under Munoz and they are set to take on West Bromwich Albion tonight.
