Wellman, in charge of the defensive group at the club, has pinpointed a number of key areas in which the team is looking to improve ahead of the upcoming season.
""There is no doubt that for us to get to the level we want to get to, we need to be bigger and stronger and to be able to run out games,” he said.
“We felt that there were times last year, particularly against the better teams, when we struggled in those areas.”
Wellman is confident the team can improve on last season, with a strong platform already set during the off season.
“We have been able to power a lot of work into the guys pre-Christmas and get them to a stage where we have laid a pretty good foundation,” Wellman said.
