The Rangers boss was disappointed that having taken a 1-0 lead the team did not captalise and ended up leaving Vicarge Road with a 3-1 defeat.
"I think when we went a goal up we showed a bit of quality. it was a great finish from Patrick Agyemang," Magilton said after Monday night's match.
"But then there has to be a collective will and desire to get a result but in the last few games we haven't shown that so one or two harsh questions have to be asked.
"At the minute everything a team is hitting against us is going into the net.
"Most Championship sides go through periods like that."
