"Really, it is best for me to express my disappointment internally. However, the players have been made fully aware that their performance at Southend was not acceptable to either myself or to Brian [Little].
"It's vital that we re-group, make sure we beat Shrewsbury at home and then look to do something about our away form. We've got to stay positive. Promotion is still a realistic aim although failing that, we must make sure we finish in a play-off place.
"We are aware criticism is starting to mount. We have to pull together and keep battling. If that means developing a siege-like mentality and grinding out a few results then so be it."
Meanwhile, Pearson has also spoken on the Glen Crowe situation. Crowe will be watched by City's head scout Derek Bell on Friday, and the club may may an approach in the summer when he is available on a free transfer.
"Derek will go over on Friday and have another look at Glen in action but at the minute that's as far as it goes.
"We have former Leeds United man Ian Baird keeping his eye on the Irish scene and there are seven or eight players who we have been keeping tabs on."
With Gary Alexander out for two games through suspension, loan cover is an option. However, Pearson is looking for Rodney Rowe to step in and make his mark.
"At this moment in time we're not looking to bring someone in on loan to cover Gary.
"I would have thought it's the perfect opportunity for Rod to show he has a part to play in our longer term plans. I keep hearing he can score goals at this level of the game. Now is the time for him to prove it."
Rowe has scored just once this season after signing a year ago.
