A 2-0 loss at home to Brackley Town will force the manager to act and he could be set to push through some new signings in light of their second round replay defeat.
Part of Pennock’s problem was that just two of his 18-man squad elected to stay in hotels near to Holker Street instead of travelling on the day.
The majority of Barrow’s players live out of the area and their manager wanted them ready instead of facing hours on the road.
“It was an awful performance - but what it has done is made my mind up on a few things,” he told Radio Lonsdale.
“We were just not good enough at the end of the day, but we’ve now got to forget this as quickly as possible. We’re not going to go anywhere if we keep performing like that.
“I’ve made my mind up on a few things and over the next few days there will be some movement for sure."
He added: “The players don’t all live in the area, I wanted them to all stay in hotels the night before and I asked them who did and only two of them put their hands up.
“To stay up would have cost them £25, so it’s not good enough. They have to give back a little bit back.
“I want to make this club as professional as possible and to take it was far as we can but we have to all be pulling in the same direction.”
