"Some big decisions need making now in terms of going forward because I envisage this league being tougher than it's ever been," Cox told the club's website. "For us to progress, we do need to add to the quality that we've got.
"We've got a hell of a start, the games come thick and fast - Saturday, Tuesday, Saturday, Tuesday.
"Our decision making is now key to make sure that we've covered every eventuality going into the first two months of the season. You can find yourself trying to catch up with the teams that have catered for and prepared for everything to come."
