Pearson insists is prepared to snap up maverick talent if necessary.
He said: "When you strengthen the side it is about doing that. If it is just a like for like you need something that is different.
"A lot of the time that has to be technical but they still need to fit in. It's not just success in terms of results. There is a more positive culture.
"But I don't want to just sign angels, if players are available that will make us more capable to win games we will take that into consideration.
"People like to pigeon hole you and say we will only build conservatively. That's not always the case.
"Some of the players we have tried to sign - and have not materialised - will have surprised a few people."
