The manager, who saw his side defeat Plymouth Argyle during the opening day of the season, admitted that while it is still early days he is keen to see his side become more competitive, and has sought to turn several aspects of training into a competition between the various groups.
Speaking via the Express & Star, Dean said; "It’s very early days. It’s just little things that have been tweaked but it’s something the staff and I drive home throughout the week.
"There are punishments with everything. If they lose in training, the losing team has to put all the equipment away. It’s just little bits like that. Psychologically, I want to get into their head. I want them to want to win at everything they do.
"Monday to Friday, against each other, I want them to have a winning mentality. I want there to be a winning mentality all around the football club."
