"Consistency is the biggest thing for the group," he said.
"We were terrific at the weekend but you have to be able to put some runs of games together - if not you will make two or three steps forward and then take one or two back.
"Maybe that has been the nature of the group over the last couple of years.
"We are looking to improve that and there is an awful lot of work to do."
